Dozens of House Republicans opted not to join 126 of their GOP colleagues in signing onto an amicus brief in support of the Texas lawsuit aimed at overturning the election results in four key states that were key to securing President-elect Joe Biden's (D) win.

The brief, which was filed on Thursday, states that it "presents [our] concern as Members of Congress, shared by untold millions of their constituents, that the unconstitutional irregularities involved in the 2020 presidential election cast doubt upon its outcome and the integrity of the American system of elections."

Texas Attorney General Ken Paxton (R) filed the lawsuit to the Supreme Court on Tuesday. The suit targeted results in Georgia, Michigan, Pennsylvania and Wisconsin, claiming the states' mail-in voting efforts during the pandemic were unconstitutional. Attorneys general from 18 other red states also joined the effort, which the Supreme Court rejected Friday.

Rep. Mike Johnson (La.) — a top ally of President Trump who serves as chair of the Republican Study Committee and will soon join House GOP leadership — helped lead the push for support among Republican lawmakers. Johnson said with more time he believes additional members would have signed onto the brief.

"As I mentioned to the president on a phone call last night, the names on the brief itself is not necessarily an indication of a complete list of House Republicans who are supportive of the legal efforts and the overall importance of ensuring the integrity of our election system," he told The Hill in an interview on Friday.

"It was merely a function of the clock, and that I ran out of time to address some of the kind of detailed, really minor concerns that some of the members had about just particular lines or arguments in the brief. And we did at one point just simply have to cut it off and file."

While the majority of House Republicans signed on, some critics close to Trump argued they thought the move set a bad precedent moving forward.
