Rep. Louie Gohmert (R-Texas) is continuing his push to reverse the results of the presidential election by trying to legally force Vice President Mike Pence to override the electors when votes are finalized by Congress on Jan 6.

In a legal brief filed this morning, attorneys for Gohmert responded to Pence's argument that they should have sued the House and the Senate, not the vice president in his presiding role.

Gohmert's attorneys wrote that there are 140 House members who are expected to object to the congressional certification of the Electoral College vote on Wednesday.

"On January 6th, a joint session of Congress will convene to formally elect the President. The defendant, Vice-President Pence, will preside. Under the Constitution, he has the authority to conduct that proceeding as he sees fit," they wrote.

"He may count elector votes certified by a state's executive, or he can prefer a competing slate of duly qualified electors. He may ignore all electors from a certain state. That is the power bestowed upon him by the Constitution."

Gohmert's attorneys say Gohmert and the "over 140" House members will object on Wednesday due to "mounting and convincing evidence of voter fraud."

"For over a century, the counting of elector votes and proclaiming the winner was a formality to which the prying eye of the media and those outside the halls of the government paid no attention. But not this time," they wrote.

"This country is deeply divided along political lines," the filing adds. "This division is compounded by a broad and strongly held mistrust of the election processes employed and their putative result by a very large segment of the American population."

A small group of Michigan's GOP would-be electors also intervened in the case, and a Biden elector from Colorado did the same in support of Pence.

The Senate voted on Friday to override President Donald Trump's veto on the defense spending bill in a rare New Year's Day session.

The stinging rebuke by members of Trump's own party represents the first time in his term that a veto has been overturned.

The vote was 81-13. A supermajority is needed to override a presidential veto.

Sen. Mitt Romney, R-Utah, confirmed today that Mitch McConnell, the Senate majority leader, called the upcoming joint session of Congress on Jan. 6, which will affirm the results of the presidential election, "the most consequential vote" of his lengthy tenure.

"I see that as a statement that he believes it's a -- it's a referendum on our democracy," Romney told reporters.

Sources said that McConnell asked Sen. Josh Hawley, R-Mo., on a New Year's Eve call with Republicans to explain to his colleagues why he is planning to object to the certification of Biden’s electoral win during the joint session. McConnell had privately warned his colleagues weeks ago against doing this as it would put his conference in the position of having to oppose Trump (and thereby his base) publicly.

Hawley, in joining the last-ditch bid by Trump's House allies to overturn the election results, said he objected to states not following their election laws.

"At the very least, Congress should investigate allegations of voter fraud and adopt measures to secure the integrity of our elections," Hawley said in a statement. There has been no evidence of widespread election fraud.

In a very rare New Year’s Day session, Senate GOP leadership rejected two attempts to debate and vote on the House-passed CASH Act, which would give most Americans $2,000 in direct COVID relief payments. It was an effort by both Sens. Chuck Schumer and Bernie Sanders.

Republicans are continuing to argue that the House bill —- which would allow those making up to $350,000 to receive some cash under the act, albeit a smaller amount than those making less -- amounts to "socialism for the rich."

The chamber’s socialist, Sen. Sanders -- continued to argue that Republicans were “hypocrites” —- blocking this effort but approving big tax breaks for the rich.

He was joined by conservative Sen. Josh Hawley, who slammed the fight by his own leadership.

“With all due respect, this doesn’t seem to be Republicans against Democrats. This seems to be the Senate against United States of America,” said Hawley.

Biden’s transition held its weekly press briefing Wednesday, hammering home the same messaging the president-elect delivered himself earlier this week on transition delays.

The team took aim at the Department of Defense and Office of Management and Budget for their lack of cooperation in the transition and also previewed some of the “day one” policy actions Biden would take once in office.

Transition spokesperson Yohannes Abraham stressed that not working with career OMB officials is hindering and needlessly delaying the team's work on COVID-19.

“There are also health and economic repercussions to this obstruction. OMB is integral to our federal government efficiently and effectively addressing COVID,” Abraham said. “OMB leadership's refusal to fully cooperate impairs our ability to identify opportunities to maximize the relief going out to Americans during the pandemic.”

When pressed on specific types of obstruction the transition was facing, Abraham added that the DOD has not had a meeting with the transition in 11 days, following DOD’s announcement that meetings would cease over the holidays (the DOD said this was a mutual agreement, which the Biden team has denied). Abraham also said DOD held only three meetings with the Biden team after ascertainment and before the holiday break announcement.

Jen Psaki, Biden's pick for White House press secretary, also spoke of some of the policy actions Biden plans to take immediately when he takes office on Jan. 20.

She announced the Biden administration will issue a memo that halts so-called “midnight rules” from the Trump administration, citing a Department of Labor rule the Trump administration is expected to publish in January that would make it easier for businesses to classify workers as independent contractors to circumvent paying overtime, minimum-wage and other protections.

“In addition to the regulatory freeze memo, President-elect Biden has promised to rescind harmful Trump executive orders, and deliver on our promises and the promises he and Vice president-elect Harris made on the campaign trail, including by reinstating protections for dreamers, rejoining the Paris Climate Accord, or reversing President Trump's environmental rollbacks that have made our air and water dirtier and protecting and strengthening the Affordable Care Act to lower health care costs and expand access to care,” Psaki said.
