After days of opposition and hours before the federal government was going to shut down, President Donald Trump signed the $900 billion coronavirus relief package, the White House announced Sunday night.

Congress passed the legislation last Monday after months of negotiations in the Senate. The package includes $600 checks for Americans who earn less than $75,000 per year, half of the $1,200 checks that were mailed out earlier this year.

After its passage, Trump initially called for the bill to be revised to include $2,000 checks and refused to sign it until his call was answered. However, he didn’t officially say he would veto it.

In the statement, Trump referred to COVID-19 as “China Virus,” blamed Democrat-run states for shutdowns and continued to make baseless claims about voter fraud in the 2020 election. He also said “wasteful items need to be removed” from the bill and continued to push for the $2,000 checks.

Democratic leaders in both houses backed the $2,000 check plan, but the GOP leadership rejected it. In a statement, Senate Majority Leader Mitch McConnell applauded Trump for signing the package and preventing a shutdown “at a time when our nation could not have afforded one.”

House Speaker Nancy Pelosi said in a statement that the relief bill is a “down payment on what is needed to crush the virus.” She said House Democrats will bring legislation on the $2,000 checks to the House floor Monday.

'This is the beginning of a very painful period for the Republicans': Frank Luntz

Sen. Bernie Sanders, one of the leading advocates for government-issued direct payments to Americans amid the COVID-19 pandemic, argued Sunday that despite his -- and President Donald Trump's last-minute -- reservations about the size of the checks within the currently stalled relief bill, it needs to be signed immediately.

"My view is that, given the terrible economic crisis facing this country, yes, we do need to get $2,000 out to every working-class individual in this country, $500 for their kids -- but you can't diddle around with the bill," Sanders, I-Vt., told ABC News Chief White House Correspondent Jonathan Karl on "This Week" Sunday.

'Sign the bill, Mr. President,' then we can pass $2,000 payments: Sanders

Though the relief package, as passed last week by Congress, contains checks for $1,400 less than the senator -- and later, Trump -- lobbied for, Sanders proposed an alternative solution in a directive to the White House.

"Sign the bill, Mr. President, and then immediately -- Monday, Tuesday -- we can pass a $2,000 direct payment for the working families of this country," Sanders said.

Republican Maryland Gov. Larry Hogan on criticized President Donald Trump for not raising his objections to the bipartisan, $900 billion COVID-19 relief bill until after Congress passed it.

"Here we are, you know, after all this work went on," Hogan told ABC News Chief White House Correspondent Jonathan Karl on "This Week" Sunday. "Both parties were so far apart in the House and the Senate. The problem solvers caucus, some -- some really bipartisan folks on both sides of the aisle brought everybody to the table. They reached an agreement."

"Secretary (Steven) Mnuchin worked together with them and made commitments on behalf of the administration, and then -- not eight months before or even eight days before but after it was passed -- then the president raises these objections? Millions of people are going to suffer," he added.

A Dominion Voting Systems employee has filed a defamation lawsuit against President Donald Trump, attorneys Sidney Powell and Rudy Giuliani, among others, alleging they helped elevate a "false and baseless" conspiracy theory about him as part of their election rigging [claims[() against the voting machine company.

The suit marks the start of what could be an onslaught of litigation against the president and his allies, who mounted challenges to the election based on false allegations of fraud and fierce conspiracy theories. Some conservative outlets in recent days have begun airing retractions as the threat of litigation looms.

Eric Coomer, the Director of Product Strategy and Security for Dominion, says he has faced death threats and harassment as a result of the "baseless and unequivocally false" conspiracy theory about him, which claimed he had admitted to rigging Dominion machines against Trump on an "Antifa conference call."

"Without concern for the truth or the consequences of their reckless conduct, Defendants branded Dr. Coomer a traitor to the United States, a terrorist, and a criminal of the highest order," Coomer wrote in his complaint. "While this theory has been thoroughly rejected, its immediate and life-threatening effects remain very real."

The suit, filed in state court in Colorado, is separate from the heavy legal challenge Dominion as a company is expected to mount on its own against Sidney Powell.

In his complaint, Coomer says the threats have escalated to the point where he had to leave his home and "sever ties" with friends and family to stay in seclusion after the theory-- part of a broader conspiracy theory that the Dominion voting machine company rigged the election for Biden-- went viral on social media.
