A West Virginia lawmaker was among the people -- mostly pro-Trump protesters -- who broke into the U.S. Capitol on Wednesday.

Del. Derrick Evans took a video of himself and others rushing into the building after attacking Capitol police. In it, he is seen wearing a helmet and yelling, "We're in! Keep it moving, baby!"

Once inside, Evans walked around the Capitol Rotunda, which is filled with historical works of art, and yelled, "No vandalizing!"

He has since deleted the video from his social media.

According to The Associated Press, State House of Delegates Speaker Roger Hanshaw said Evans will need to "answer to his constituents and colleagues regarding his involvement in what has occurred today."

"I want to thank everyone for their prayers today," Evans wrote in a Facebook statement after the Capitol break-in. "I am on the bus headed back home to WV. As many of you know, for the last few years I have traveled across the country to film many different events. Today, I had the opportunity to film another event in DC. I want to assure you all that I did not have any negative interactions with law enforcement, nor did I participate in any destruction that may have occurred. I was simply there as an independent member of the media to film history."

Biden officially announced key nominations for the U.S. Department of Justice on Thursday.

Judge Merrick Garland is his nominee for attorney general, Lisa Monaco is his nominee for deputy attorney general, Vanita Gupta is his nominee for associate attorney general, and Kristen Clarke is his nominee for assistant attorney general for the department's civil rights division.

Biden said he is "honored" that the nominees have "accepted this call to serve at such a critical time in our nation’s history."

"Our first-rate nominees to lead the Justice Department are eminently qualified, embody character and judgment that is beyond reproach, and have devoted their careers to serving the American people with honor and integrity," Biden said in a statement Thursday. "They will restore the independence of the Department so it serves the interests of the people not a presidency, rebuild public trust in the rule of law, and work tirelessly to ensure a more fair and equitable justice system. They are among the most accomplished legal minds in our country who also reflect the best of America’s full range of talents and background."

Hours after a pro-Trump mob broke into the U.S. Capitol to protest the results of the 2020 election, congressional tellers have ascertained Joe Biden and Kamala Harris have won.

The announcement was made by Minnesota Sen. Amy Klobuchar at 3:39 a.m. Thursday.

Vice President Mike Pence then repeated the totals at 3:40 a.m., first for president, then for vice president.

Biden will take Trump's place in the White House on Jan. 20.

Rep. Louie Gohmert and other House Republicans attempted to object to Wisconsin but did not have a senator join the objection. Gohmert said a senator withdrew his objection.

Biden and Harris finished with 306 electoral votes, while Trump and Pence finished with 232.

In a statement tweeted by White House Deputy Chief of Staff Dan Scavino following the news, Trump said: "Even though I totally disagree with the outcome of the election, and the facts bear me out, nevertheless there will be an orderly transition on January 20th. I have always said we would continue our fight to ensure that only legal votes were counted. While this represents the end of the greatest first term in presidential history, it's only the beginning of our fight to Make America Great Again!"

This is the first time Trump has publicly accepted Biden's victory and agreed to a peaceful transfer of power.

After two hours of heated debate, the House of Representatives rejected the Republican objections to certify Pennsylvania's Electoral College ballots early Thursday.

There were 138 House Republicans who voted to sustain the objection, while 64 voted against it and 218 Democrats also voted against it.

No House Democrats voted in favor of the objection, while a majority of House Republicans (68%) did.

The GOP effort to overturn the will of Pennsylvania voters failed in the Senate just a few hours earlier, after the upper chamber completely bypassed debate and went straight to a vote.

With no further objections anticipated, Congress is expected certify Pennsylvania's Electoral College ballots. Congress will then continue counting electoral votes from the rest of the states.

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.
