The House has rejected the challenge to Arizona's electoral votes, 121-303, with most Republicans supporting the challenge.

There were 121 Republicans, 57% of the conference, who voted in favor of the objection, including GOP Leader Kevin McCarthy of California, and House Minority Whip Steve Scalise of Louisiana.

On the other side, 220 Democrats voted against the objection, joined by 82 Republicans. Two Democrats and five Republicans did not vote.

Speaker Nancy Pelosi announced that the House will soon move back into joint session with the Senate, where the certification of the electoral votes will continue alphabetically by state.

The next challenge expected is Georgia's votes, but it's unclear if House Republicans still have a senator to help them force debate and a vote.

Hours after the Senate began debate counting the Electoral College votes, the full body voted 93-6 not to take up the objections to Arizona's Electoral College votes.

Senators Ted Cruz, Josh Hawley, Cindy Hyde-Smith, John Neely Kennedy, Roger Marshall and Tommy Tuberville all voted in favor.

Before the pro-Trump mob stormed the Capitol Wednesday, 13 Republican senators said they would object to the state over baseless claims of fraud. Seven changed their position after the violent siege ended and Congress returned to the Senate chamber.

Several senators will continue speaking on the floor while the House wraps up their debate on the objection to Arizona's electoral results, Senate Republican Leader Mitch McConnell said.

White House deputy press secretary Sarah Matthews has resigned in response to what happened at the Capitol Wednesday.

Matthews said in a statement she was "honored" to serve the administration and "proud" of the policies it enacted, but added "our nation needs a peaceful transition of power."

"As someone who worked in the halls of Congress I was deeply disturbed by what I saw today. I'll be stepping down from my role, effective immediately," she said in her statement.

Multiple sources tell ABC News President Trump rebuffed efforts for quite some time to call in the National Guard Wednesday afternoon as chaos escalated at the U.S. Capitol, and steps weren't made until a few White House officials intervened for "the sake of the country."

Sources tell ABC News the aides explained to Trump that if action was not taken other protesters could mobilize across the country and the situation would only grow more dire.

Sources say the president is fuming mad inside the White House, unclear what his next move or action could be. He is described by one strong source as "stewing."

Vice President Mike Pence, stumping for GOP Georgia senators on the eve of runoff elections there, vowed Republicans will have "our day in Congress" to contest the Electoral College results while urging supporters to put their immediate focus on defending the party's majority in the Senate.

"I know we’ve all got our doubts about the last election," Pence told hundreds of mostly maskless supporters inside a church in Milner, Georgia. "And I want to assure you I share the concerns of millions of Americans about voting irregularities. And I promise you, come this Wednesday, we’ll have our day in Congress. We’ll hear the objections. We’ll hear the evidence. But tomorrow it’s Georgia’s day."

Recent polls show tight races between sitting GOP Sens. David Perdue and Kelly Loeffler and Democratic contenders Jon Ossoff and Rev. Raphael Warnock -- forcing star power to the Peach State on the eve of the election including visits from Trump and Biden later on Monday.
