A group of Republican lawmakers have filed a lawsuit against House Speaker Nancy Pelosi over the chamber’s new proxy voting system, a challenge to the rule that is set to be used for the first time on Wednesday.

The House developed and passed its new — and historic — proxy voting rules earlier this month, allowing members unable to come to Capitol Hill due to the coronavirus pandemic to designate another lawmaker as their “proxy” and cast floor votes on their behalf.

The goal was to allow lawmakers to have a voice if they could not travel to Washington safely due to the pandemic. It came after the House passed a number of coronavirus packages that amounted to about $3 trillion, bills where most lawmakers did not have much of a say in negotiations.

While the unprecedented rule change passed the chamber, no Republicans voted in favor of the measure with some calling into question the Constitutionality of the change. 

The lawsuit, led by House Minority Leader Kevin McCarthy, outlines this argument and details that under the Constitution, a majority of lawmakers must be present in order to take up business and vote on legislation.

“It is a brazen violation of the Constitution, a dereliction of our duty as elected officials, and would silence the American people’s voice during a crisis,” McCarthy, R-Calif., said in a statement officially announcing the lawsuit. “Although I wish this matter could have been solved on a bipartisan basis, the stakes are too high to let this injustice go unaddressed.”

McCarthy continued, arguing that while the Constitution allows for the House to dictate its own rules, it does not give authority to override the Constitution. “Rapid and robust legal relief is necessary,” he says, though Republican aides note that a court is not likely to interject before the House votes this week using the proxy system. 

Twenty House Republicans have signed on to the lawsuit, including members of House leadership, such as Republican Whip Steve Scalise, R-La., and GOP Conference Chairwoman Liz Cheney, R-Wy. Four members of the public, each from different states, have also signed on.

The lawsuit targets Pelosi, along with the House clerk and sergeant-at-arms, and was filed in the D.C. federal district court Tuesday evening, McCarthy’s office said. 

Americans took to twitter to show how pleased they are with the suit after Fox news twitted the story. Here are screenshots of some of the reactions.
