WASHINGTON (Reuters) - The Democratic-controlled U.S. House of Representatives voted on Friday to restore funding for some federal agencies that have been shut down by a fight with President Donald Trump over border wall funding, as an estimated 800,000 government workers, from tax collectors to FBI agents, missed their first paycheck.

But a full resumption of government operations at those agencies did not appear in sight. The Senate adjourned for the weekend without taking action, and Senate Republican Leader Mitch McConnell has said he will not bring the House bill up for a vote. Republicans who control the Senate have so far stood with Trump and insisted that any spending bills include money for his wall.

The House bill, which passed 240-179 with only 10 Republicans supporting it, would restore funding for the Interior Department and the Environmental Protection Agency, two of the agencies that have been without funding since Dec. 22 amid the standoff over the proposed wall along the U.S.-Mexico border. The $35.9 billion bill provides $6 billion more than Trump requested.

Facing the prospect of the longest U.S. government shutdown in history, Trump has said he might declare a national emergency to bypass Congress to get funding for his wall, which was a central promise of his 2016 presidential campaign.

Entering its 21st day, the partial shutdown on Friday tied the record for the longest in U.S. history.

Miami International Airport said it will close one of its terminals early over the next several days due to a possible shortage of security screeners, who have been calling in sick at twice the normal rate.

A union that represents thousands of air traffic controllers sued the Federal Aviation Administration on Friday, saying it had violated federal wage law by failing to pay workers. It is at least the third lawsuit filed by unions on behalf of unpaid workers.

Some 800,000 federal workers did not receive paychecks that would have gone out on Friday. Some have resorted to selling their possessions or posting appeals on online fundraising outlets to help pay their bills.

"Most of them are living from paycheck to paycheck and now they approach this day on Friday having moved from paycheck to no check," Democratic Representative Elijah Cummings said in debate on the House floor.

The head of the U.S. Secret Service, which is responsible for protecting Trump, warned employees that financial stress can lead to depression and anxiety. "Keep an eye out for warning signs of trouble," Director R.D. "Tex" Alles wrote in a memo seen by Reuters.





PENCE PROMISES BACK PAY

Vice President Mike Pence said Trump will sign legislation passed in Congress that will provide back pay to federal workers once the government reopens.

"Your families will get your paychecks," he told U.S. Customs and Border Protection officers at the agency's Washington headquarters.

Separately, Senator Rob Portman and eight other Republican senators introduced legislation that would permanently outlaw the closing of government operations during budget fights, underscoring the growing frustration in Washington.

During his presidential campaign, Trump repeatedly pledged that Mexico would pay for the wall, which he says is needed to stem the flow of illegal immigrants and drugs. But the Mexican government has refused and Trump is now demanding that Congress provide $5.7 billion in U.S. taxpayer funding for the wall.

Democrats in Congress call the wall an ineffective, outdated answer to a complex problem.

With no Capitol Hill compromise in sight, Trump publicly ruminated on Thursday during a trip to the Texas-Mexico border trip about declaring an emergency.

A close Trump confidant judged the time for such a step had come. Republican Senator Lindsey Graham said in a statement: "It is time for President Trump to use emergency powers to fund the construction of a border wall/barrier. I hope it works."

Critics of the national emergency strategy have said it may be illegal. In any case, it was almost certain to trigger an immediate court challenge from Democrats, including an accusation of trying to circumvent Congress' power over the national purse strings.

An emergency declaration would come with risks. Even some of Trump's fellow Republicans in Congress have signaled worries about such an action. Given that the Constitution gives Congress the power to set spending priorities and appropriate money, they worry about a tough legal fight and an unwise precedent.

"I don't think he should do that. It's a bad precedent," Republican Senator Chuck Grassley said on CNBC. "It seems to me that

An emergency declaration, however, would allow the government to be fully reopened while the judges weigh the case, which could take months.
