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."

Georgia election official Gabriel Sterling, a Republican, at a press conference on what he called "anti-disinformation Monday," ran through major voter conspiracies pushed by Trump, his allies and far-right media outlets and debunked them one-by-one in an effort to restore faith in Georgia's election system.

"The reason I'm having to stand here today is because there are people in positions of authority and respect who have said their vote didn't count and it's not true," Sterling said, stressing to Georgians that their votes count ahead of critical runoffs in the state which will determine the balance of power in the U.S. Senate.

"It's Whac-A-Mole again. It is Groundhog Day again. I'm going to talk about the things I've talked about repeatedly for two months, but I'm going to do it for one last time," Sterling said, adding he "screamed" at the radio upon hearing audio of the phone call between Trump and Secretary of State Brad Raffensperger because theories Trump questioned have already been "thoroughly debunked."

For example, Sterling, responding to those who claim there were roughly 2,500 people who voted without being registered, said, "Let's just be clear about this: you can't do it!" He said, "So that number is zero," going on to debunk other theories.

Asked if he believes, as some have said, that Trump's phone call was an attack on democracy, Sterling said he'd leave others to make that decision before adding he felt it was "out of place."

"I found it to be something that was not normal -- out of place -- and nobody I know who would be president would do something like that to a secretary of state," Sterling said.

Asked about Raffenperger's desire to have the phone call recorded and whether he was concerned about anything improper being said or needing to release it later, Sterling said it was recorded "out of an abundance of caution"

"I think given the environment we're in right now, the political situation that we're in, the history of the president, knowing that he sometimes doesn't necessarily characterize things as they might have actually occurred, it was out of abundance of caution," Sterling said.

"I'm sure the president's side may have recorded it, too. They may have been the ones who leaked part of that, too," he added.
