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."

In an interview on Fox News Monday morning, Republican senatorial candidate David Perdue said that while he and his wife have "repeatedly" tested negative for coronavirus, he is still quarantining after coming into "close contact" last week with a campaign staffer who tested positive and hopes to participate in

"I’m going to participate hopefully tonight by virtually in this rally, but I’m so excited that President Trump is coming again," Perdue said, going on to paint the dire picture of the country if Democrats win.

Asked what he wants to hear the president say Monday, Perdue said: "First of all this is the last opportunity we will have to protect everything that we’ve accomplished in the last four years. The second thing is the last line of defense to stop the Democrats from perpetrating this radical socialist agenda. It’s as simple as that." 

As he did Sunday, Perdue blasted disclosure of the call between Trump and Secretary of State Brad Raffensperger and defended the president.

"To have a state-wide elected official, regardless of party, tape unknowing -- to tape without disclosing a conversation -- private conversation of the president of the United States and then leaking it to the press is disgusting," Perdue said.

When asked if he was concerned that GOP voters may be discouraged from participating in the aftermath of a general election Republicans continue to contest, Perdue said, "Well that’s what the Democrats want." Trump himself acknowledged post-election chaos may hinder turnout in the runoffs during his call with Raffensperger Saturday -- and blamed the secretary for it.
