After meetings into the early morning hours failed to produce an agreement on the massive coronavirus relief plan, members of Congress will reconvene at noon Monday in hope of approving the next phase of the agreement.

Senate Majority Leader McConnell had recommended the Senate reconvene Monday morning. but Minority Leader Chuck Schumer said he was having ongoing meetings with Treasury Secretary Steven Mnuchin, and that he was hopeful of having an agreement by noon.

McConnell said he was concerned about the delay rattling the financial markets when they open in the morning, but nevertheless adjourned Sunday's marathon session and scheduled the Senate to be back in session at noon Monday.

The nearly $2 trillion plan is expected to provide broad financial relief to American families and businesses, including cast payments directly to individuals.

10:42 p.m.: Negotiations continue after Senate votes down relief plan

Lawmakers are working to find common ground after the Senate failed to advance the coronavirus relief package, now expected to reach close to $2 trillion.

Senate Democrats on Sunday evening failed to back a procedural vote to advance the measure over concerns that it prioritizes corporations over individuals.

Sen. Joe Biden accused President Trump and Senate Majority Leader Mitch McConnell of "trying to put corporate bailouts ahead of families."

"The White House and the Senate Republicans have proposed a $500 billion slush fund for corporations, with almost no conditions. Donald Trump's Treasury Secretary would decide which big businesses get how much, and he can give out billions with virtually no strings attached," Biden said Sunday night. "The Trump Administration could even allow companies to use taxpayers’ money for stock buybacks and executive pay packages, and they don’t have to tell Americans where the money is going for months."

Senator Chuck Schumer, the Senate minority leader, said he hoped a compromise would still be reached as discussions continued Sunday night.

McConnell said late Sunday night that the Senate will vote again at 9:45 a.m. Monday, "unless we finally reach an agreement between now and then."

“Our nation cannot afford a game of chicken," McConnell said.

"The federal government will be funding 100% of the cost to deploy National Guard units to carry out approved missions to stop the virus while those governors remain in command," Trump said. "I spoke with all three of the governors today, just a little while ago, they're very happy with what we're doing."

In addition, Trump said, "I directed FEMA to supply the following: Four large medical stations with 1,000 beds for New York, eight large federal medical stations with 2,000 beds for California. and three large federal medical stations and four small federal medical stations with 1,000 beds for the state of Washington."

Pete Gaynor of the Federal Emergency Management Agency said that medical supplies, including personal protective equipment, will be arriving in the affected states within 42 hours.

Also at the briefing, officials urged that testing be prioritized toward the neediest cases.

"We want people that have been checked into a hospital, that are being treated for what they expect to be coronavirus, to receive those tests more quickly.," said Vice President Mike Pence.

Members of the task force said that 254,000 Americans have been tested for COVID-19, with 30,000 of those -- 11.8% -- testing positive.

6:57 a.m.: Russia’s military is sending medical aid to Italy

Russia’s military is sending medical aid to Italy to help in its fight against the coronavirus epidemic, including disinfection vehicles and military virologists.

Russia’s defense ministry in a statement announced military transport planes will be delivering eight mobile brigades of military medics, special disinfection vehicles and other medical equipment to Italy, starting from Sunday.

It followed a phone conversation between president Vladimir Putin and Italy’s prime minister Giuseppe Conte, during which Putin offered help.

The move obviously highlights the EU’s relative failure so far to aid Italy in the epidemic and follows China sending a plane-load of medics to help. The authoritarian governments see this as a diplomatic and PR opportunity. Italy was already one of the friendliest countries to Russia in the EU and this obviously won’t go unremembered.
