In a roller-coaster day of coronavirus-related events, President Donald Trump declared a national emergency Friday to provide disaster funding, speed up the U.S. response to the crisis and offer "maximum flexibility" to attack the problem.

Trump, speaking from the White House Rose Garden, said the move would free up $50 billion in additional disaster funding and would also allow the department of Health and Human Services to waive regulations and laws to deliver coronavirus testing quicker.

The president said the emergency measures will allow "maximum flexibility to respond to the virus and to care for patients." He said some of the steps could open up such local innovations as drive-through testing.

"No resource will be spared," Trump said.

Word of the announcement comes amid efforts by the House to agree with the administration on a massive federal response to the crisis following a week of huge swings on Wall Street.

The administration stepped up its efforts in the immediate aftermath of the World Health Organization declaring the coronavirus outbreak a pandemic and the global death toll surpassing 5,000. Confirmed cases in the U.S. exceeded 1,700, and House Speaker Nancy Pelosi said Friday there have been 41 deaths.

The fallout from the coronavirus crisis keeps coming, with schools shutting down, iconic sports events postponed and political actors weighing in.

Here's the latest on the outbreak of COVID-19:

Cruise lines suspend operations

Major cruise lines including Carnival, Royal Caribbean, Norwegian, and MSC will suspend sailing operations to and from U.S. ports for 30 days due to the COVID-19 pandemic, Cruise Lines International Association announced Friday.

Viking and Disney cruises announced similar measures Thursday, before the major cruise association.

The suspension will take effect at midnight Friday. CLIA said it will focused on the "safe and smooth return" of those currently at sea on ships.

President Trump tweeted Friday that the cruise suspension came "at my request."

"It is a great and important industry – it will be kept that way!" Trump wrote.

Also Friday, Canada's transport minister, Marc Garneau, said all Canadian ports would be closed to cruise ships carrying more than 500 passengers from April 2 to July 1.

At least 30 cruise ships at sea list port destinations in the USA this week, according to a USA TODAY analysis. That means upward of 100,000 people – 70% of them passengers – could look to come ashore at a range of U.S. ports.

Nursing homes restricting family visits

Nursing homes across the country are restricting visitors in an attempt to protect residents from the virus, sacrificing person-to-person visits even from family in a bid to slow the disease's spread.

The Centers for Medicare and Medicaid Services said Friday it will tell nursing homes nationwide to come up with temporary restrictions that ban visitors and nonessential personnel with a few exceptions, such as end-of-life situations, said Seema Verma, administrator of the federal agency that oversees the nation's major health care programs.

The American Healthcare Association and the National Center for Assisted Living are also advising nursing homes to restrict nonessential visits to prevent their residents from being exposed to COVID-19, the illness caused by the new coronavirus.

Hundreds of libraries closing nationwide

Library systems across the country are shutting their doors in an effort to slow the spread of coronavirus.

Los Angeles, San Francisco and Seattle all announced they were closing their libraries Friday at the end of day. Los Angeles' 73 libraries and San Francisco’s 29 will be closed through March 31. The closure in Seattle of all 27 libraries will last at least through April 13.

New York City also closed all of its 92 libraries Friday evening and will reopen on March 31.

Toledo, Ohio libraries will close beginning Sunday, March 15, with no reopening date yet set. Ten branches which are also polling places will be opened for Democratic Party Primary voting on March 17.

The Columbus, Ohio Metropolitan Library is closing all 23 locations Friday at least through April 6.

In Maryland, the library system of the city of Baltimore as well as five county library systems, Baltimore, Howard, Anne Arundel, Carroll and Hartford, were being closed over the weekend. Reopening dates varied between March 27 and March 31.

In Cincinnati, all 41 libraries that are part of the city and county library system closed March 13. The system plans to reassess the closure each week.

The Office of Commonwealth Libraries in Pennsylvania instructed all libraries to close on March 14 and remain closed through March 29.

Trump says he will be tested for coronavirus

President Donald Trump said during his Friday afternoon news conference that he would “most likely” be tested for the virus.

“Fairly soon,” he said when asked when the test would be performed. “We are working out a schedule.”

Trump met with Brazilian President Jair Bolsonaro at Mar-a-Lago in Florida last Saturday. While Bolsonaro has tested negative for the virus, on Thursday his top communications aide tested positive for COVID-19.

Trump said his decision to agree to a test had nothing to do with the Bolsonaro interaction. “Not for that reason but because I will do it anyway,” the president said.

Others who came in contact with Brazilian officials during the visit have taken other actions. U.S. Sen. Lindsey Graham, R-South Carolina, self-quarantined after attending the dinner at Mar-a-Lago.

Asked about the self-quarantine efforts, Trump said he had been told by his “many” White House physicians not to be tested for the virus.

Almost all Grand Princess passengers disembarked

Princess Cruises, a division of Carnival, says it won't sail for 60 days. Two of its ships, the Diamond Princess and Grand Princess, have experienced outbreaks of the coronavirus in recent weeks.

The Grand Princess confirmed Friday that approximately 2,450 people have disembarked and the 14 international guests who remain on the ship are awaiting transportation to their home countries.

The ship has been disembarking this week in Oakland, California. Once the final 14 passengers leave, the entire process will be complete. At least two passengers and 19 crew members on the Grand Princess tested positive for the coronavirus.

More than 700 people aboard the Diamond Princess tested positive for the coronavirus, and six of them died. The ship was first quarantined off the coast of Japan on Feb. 3. The last people got off the ship on March 1.

Some Starbucks could become drive-thru only

Some Starbucks stores in the U.S. and Canada may become drive-thru only while others could limit the number of people allowed inside in response to the pandemic, the company said.

The company might also close a store if it feels it is in the best interest of its customers, Starbucks CEO Kevin Johnson said in a letter to customers.

Any closures will be temporary and decisions will be made on a store-by-store basis.

The Seattle coffee chain has approximately 15,000 U.S. stores and 1,600 Canadian stores. Most are owned by the company but some – including locations in retail stores and airports – are run by licensees.

Starbucks has already increased the pace of sanitizing stores and put into place a temporary ban on use of personal cups or in-store mugs and glassware.

Federal student loan interest waived

President Trump said Friday he was waiving all federal student loan interest due to the outbreak. The waiver will last “until further notice,” he said.

Few details about how that might affect borrowers were available. Would it mean a smaller monthly payment, or simply that a borrower might be able to repay the principal balance back more quickly?

The Education Department did not immediately provide detail about how the president’s plan would work. Experts said that waiving interest wasn’t that helpful.

It’s really the payment that hurts borrowers, not necessarily the interest, said Antoinette Flores, the director for postsecondary education at the Center for American Progress, a left-leaning think tank. She wondered whether borrowers would be able to pause their payments without accruing interest on their loans.

Beth Akers, a senior fellow at the Manhattan Institute, a right-leaning think tank, agreed that waiving interest in this context would be “somewhat inconsequential.” But, she said, it might set a precedent for eliminating interest in the future.

Stocks welcome Trump's emergency declaration

Stocks recovered Friday following a brutal week of selling after Trump declared a national emergency to free up about $50 billion in federal aid to fight the virus. The Dow Jones industrial average finished the day up 1,985 points, or 9.4%, a day after plunging 2,352 points, for its worst loss since its nearly 23% drop on Oct. 19, 1987.

Pelosi: House to pass economic stimulus bill aimed at boosting virus testing

House Speaker Nancy Pelosi said Friday that the House would pass an economic stimulus package aimed at boosting testing for the coronavirus and to help people displaced economically by the crisis.

"The three most important parts of this bill are testing, testing, testing," she said in a televised statement. She said it would provide for coronavirus testing for everyone who needs a test — including the uninsured.

It also will secure paid leave, with two weeks of paid sick leave and family and medical leave, for those affected by the virus, she said.

The speaker called the packages "evidence-based" in its effort to tackle the virus crisis. Although some Republicans have dismissed earlier versions of the bill as a Democratic "wish-list," Pelosi negotiated the final deal with Treasury Secretary Steven Mnuchin.

Trump shakes several guests' hands at coronavirus press conference

After declaring a national emergency to combat the coronavirus outbreak, President Donald Trump shook hands with a series of corporate executives after they each made remarks at the White House podium – despite repeated advice from his own public health experts against such contact.

Only one company official, Bruce Greenstein of the home healthcare provider LHC Group, moved his hand away from Trump’s outstretched hand and offered an elbow instead.

"I like that. That's good," Trump said a bit awkwardly after elbow-bumping Greenstein.

New Jersey governor calls for Real ID deadline extension

Governor Phil Murpy said in a Facebook post Friday that he has requested a nationwide extension of the Real ID deadline.

"Today, I wrote the federal government requesting a nationwide extension of the Real ID deadline," Murphy said.

The Real ID Act requires all travelers over age 18 to present Real ID-compliant identification to fly. Many states won't issue Real ID compliant driver's licenses without several forms of proof of identify.

As of Oct. 1, 2020, fliers who do not have a Real ID or an acceptable alternative form of identification will not be able to get past any domestic airport security checkpoint.

Kentucky Derby could be delayed

Churchill Downs is dangling the possibility of postponing the 146th running of the Kentucky Derby until later this year. A decision is expected closer to race day on May 2, the company said.

The Derby has been held every year in May since 1875, except in 1945 when it was postponed by a month due to a nationwide ban on racing because of World War II.

The storied race brings an estimated $400 million to the Louisville area each year.

Churchill Downs spokeswoman Tonya Abeln issued a statement saying the company is pushing ahead with preparations for Derby 146 and would seek guidance from public health experts and federal, state and local authorities.

"Our operators are super concerned," said Stacy Roof, president and chief executive of the Kentucky Restaurant Association, which represents hundreds of local and regional restaurant owners. “They make several months of revenues off two weeks of the Derby.”

The presidential primary was slated for April 4, but will be moved to June 20.

According to the Monroe, La., Advertiser, Gov. John Bel Edwards will grant the delay.

Louisiana is the only state that has announced it will delay its primaries due to coronavirus.

FDA, HHS take steps to speed up virus testing

In an effort to speed up testing for the coronavirus, the Food and Drug Administration says it has given New York state wide latitude to approve testing locally and has created a 24-hour emergency hotline for labs having difficulty getting materials or finding other impediments to running tests.

The FDA said in a statement that it will allow the New York State Department of Health to authorize certain labs to begin testing patients after validating their tests and without first having to notify the FDA.

"These labs will interact solely with (the New York State Department of Health) which should expedite the availability of patient testing in New York State," said FDA Commissioner Stephen M. Hahn. He said the decision "demonstrates FDA’s responsiveness to the needs of our country during this time.”

In a related move, the Department of Health and Human Services says it is giving more than $1.2 million to two companies that are working on diagnostic tests that might be able to determine within an hour whether a patient tests positive for the coronavirus-related disease.

Fauci sees 'major escalation' is testing in next two weeks

Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, says the frustrating delay in testing for the disease is getting untangled and that predicts a "major escalation" in a week or two in widespread access to them.

Fauci told MSNBC's "Morning Joe" on Friday that the major involvement of the private sector in the testing process will shortly break a logjam that has limited testing for the virus.

Acknowledging said a "disconnect" in the past few weeks, he said: "Hopefully this is behind us.

"Within a week we are going to see a real escalation of testing and within two or three weeks we will see major progress," Fauci said.

On Thursday, Fauci told Congress that the nation’s testing record to date was “a failing.”

“The idea of anybody getting it easily the way people in other countries are doing it, we’re not set up for that. Do I think we should be? Yes. But we’re not,” he testified.

New York City suburb opens drive-thru virus test facility

A drive-thru coronavirus testing facility opened Friday in New Rochelle, a New York City suburb that has been hit especially hard by by spreading disease.

Gov. Andrew Cuomo said Friday that that testing at the site, which he called the first of its kind on the East Eoast, will be available by appointment only.

New Rochelle residents — particularly those who have been quarantined — will be tested first, though all Westchester County residents will be eligible to make an appointment. As of Thursday, New York had 328 confirmed coronavirus cases, with 148 of those in Westchester County.

The drive-up site features six lanes where medical personnell take swabs and send them to BioReference Laboratories for testing. The whole process takes about 15 minutes, Cuomo said.

The drive-thru was opened after the U.S. Food and Drug Administration announced it had granted New York permission to authorize 28 private labs to begin testing

New infections soar in Italy, Spain

Virus-related deaths in Italy have made their biggest single day jump — 250 — as new infections in Italy soared by more than 2,500. On Friday, three weeks to the day since the country identified its first virus cluster in the north, Italy had a total of 17,600 confirmed cases, with 1,266 deaths.

“Europe has now become the epicenter of the pandemic with more reported cases and deaths than the rest of the world combined, apart from China,” said World Health Organization Director-General Tedros Adhanom Ghebreyesus. “More cases are now being reported every day than were reported in China at the height of its epidemic.”

New infections also rose sharply in Spain, where the government put 60,000 people in four towns on a mandatory lockdown Friday.

In Madrid, many of the 2,000 infections are in nursing homes, the government was pooling intensive care units and considering offers by hotel chains to transform rooms into sick wards.

Masters tourney, Boston Marathon postponed

Following the lead of other major sports events, two iconic sports events — the Masters golf tournament and the Boston Marathon — have been postponed.

The golf tournament that was set to begin April 9 will be postponed indefinitely, the Augusta National Golf Club announced Friday, while Boston Mayor Marty Walsh said the Boston Marathon will be rescheduled for Sept. 14.

The Augusta National Golf Club's decision to postpone golf’s first major of the season comes 12 hours after PGA Tour Commissioner Jay Monahan canceled the Players Championship after one round and declared all Tour events canceled through the Valero Texas Open, which is the tournament that precedes the Masters.

Among other sports, Major League Baseball announced Thursday that it is halting spring training games and will delay Opening Day by at least two weeks due to the outbreak of coronavirus. The regular season was scheduled to begin on March 26.

The NBA suspended its season indefinitely Wednesday night after Utah Jazz player Rudy Gobert tested positive for the virus. Teammate Donovan Mitchell has also tested positive. The NHL followed suit and "paused" its season on Thursday, as did Major League Soccer.

And the NCAA, which on Wednesday said it would play its men's and women's tournaments without fans, gave in to the inevitable Thursday and canceled them.

Schools across country to shut down for weeks

Twelve states and several large urban school districts are shutting down all K-12 schools as part of a sweeping attempt to contain the spread of the coronavirus.

Ohio, Maryland, Oregon, New Mexico, Michigan, West Virginia, Virginia, Louisiana, Illinois, Wisconsin, Washington and Alabama have ordered all schools closed. The governor of Kentucky has recommended closing all schools in that state. Major metropolitan districts in Atlanta, Denver, San Francisco, San Diego, Washington, D.C. and Austin, Texas have also shuttered. And a growing number of smaller districts around the country have also chosen to close.

The actions are the first wave of widespread school closures in the U.S., and they stand to upend school and family routines for millions of children.

Thus far Washington State appears to have put the longest closure into place. There, public schools will not reopen until at least April 24 by order of the Governor. Gatherings and events of more than 250 people are banned statewide

Such closures will also throw into sharp relief the deep socioeconomic divides in American education. Disadvantaged families who rely the most on schools for stable services, such as meals and access to learning materials, will be some of the most negatively affected. Read more here.

No visitors allowed in federal prisons for 30 days

The federal Bureau of Prisons is immediately suspending inmate visitation and attorney-client meetings across its vast system for the next 30 days as a guard against the coronavirus, according to Justice Department guidelines.

Exceptions for legal visitation will be made on a "case-by-case" basis.

"Attorneys seeking an in-person visit with their client or a confidential call should contact the institution," according to the new policy. If approved, attorneys may have to be medically screened.
