Ahead of Monday’s meeting of Michigan’s 16 electors at the state Capitol in Lansing, officials announced the state legislature's office buildings will be closed due to "credible threats of violence."

The decision to close the state House and Senate offices — while the presidential electors convene in the Senate chamber to cast their votes for President-elect Joe Biden, who carried the state by more than 154,000 votes — came from a recommendation from law enforcement, officials said.

But the decision was not motivated by anticipated protests outside the capitol, according to a statement from Amber McCann, a spokesperson for Senate Majority Leader Mike Shirkey.

"The Senate has closed its own workspaces tomorrow based upon recommendations from law enforcement. The decision was not made because of anticipated protests, but was made based on credible threats of violence," McCann said late Sunday night, without adding any details about the threats. 

"Senate leadership does not have the authority to close the Capitol. That decision is made by the Capitol Commission," she continued. 

A spokesperson for Lee Chatfield, Speaker of the Michigan House, confirmed that the closures apply to the lower chamber as well. 

Amid the "safety concerns," state lawmakers will be working remotely on Monday, a Democratic member of the House tweeted.

Incoming White House Senior Adviser Louisiana Rep. Cedric Richmond, appeared on CBS' "Face the Nation" on Sunday, but revealed very little about the incoming Biden transition plans for vaccine distribution or dealing with the newly announced investigation of Hunter Biden’s taxes. However, Richmond stressed in his interview that Republicans were very aware that Biden would be president on Jan. 20.

When asked about congressional Republicans largely refusing to recognize President-elect Biden’s victory, Richmond pushed back, saying it was a small portion of the party afraid of Trump.

"They recognize Joe Biden's victory. All of America recognizes Joe Biden's victory. This is just a small portion of the Republican conference that are appeasing and patronizing the President on his way out because they are scared of his Twitter power and other things. And so when it's time to govern, if we can't cooperate -- if Republicans won't meet us halfway, we will go to the American people, and we will continue to push our agenda. But this country is in far too much turmoil. And this pandemic, the economic aspects and health aspects really caused for America to get on one page -- solve this crisis and start to move forward. So -- we're not going to let them slow us down,” he said.

"I talk to Republican members of Congress all the time, and they say one thing privately, they say another thing publicly. But the one thing I will tell you is they realize he lost this election," Richmond added.

Former New Jersey governor and ABC News political contributor Chris Christie, criticized President Donald Trump and his allies' efforts to overturn President-elect Joe Biden's election victory during "This Week"'s Powerhouse Players Roundtable discussion on Sunday.

"The legal theory put forward by his legal team and by the president is an absurdity," Christie said. "The reason why the Supreme Court didn't take it is because it's an absurd idea to think that any state or any number of states, no matter how good they are, can challenge another state's right to run the election as they see fit. And, also, there's no evidence," he added.

Christie also denounced what he called were "attacks" by the president on "decent Republican governors."

"What's gotten even worse ... is the attacks by the president on good, hardworking, decent Republican governors," he said. "He's calling them corrupt, and also telling people things that aren't true," Christie said, mentioning the president's recent comments about Arizona Gov. Doug Ducey and Georgia Gov. Brian Kemp.

The president tweeted in November that Kemp was "hapless" and should "overrule his obstinate secretary of state," Brad Raffensperger -- also a Republican backer of Trump -- after the latter has refused to intervene to help Trump.

"The governor's done nothing," Trump also said in a Fox News interview. "He's done absolutely nothing. I'm ashamed that I endorsed him."

On Dec. 12, the president tweeted, "Who is a worse governor, @BrianKempGA of Georgia or @dougducey of Arizona???" as part of a series of tweets blasting both governors since the presidential election.

Former Vice President Al Gore, 20 years ago today said, "Let there be no doubt. While I strongly disagree with the court's decision, I accept it."

Twenty years ago during the 2000 presidential election, the campaigns of George W. Bush and Al Gore fought in court for a chaotic 36 days over a ballot recount in Florida and certification of final results. The U.S. Supreme Court ultimately intervened, reversing a state Supreme Court ruling, to end the counting and effectively deliver the presidency to Bush.

At the center of the controversy were irregularities in the way ballots were marked -- so-called "hanging" or "dangling" chads -- which famously required interpretation of voter intent.

While the U.S. Supreme Court has twice refused to hear pro-Trump challenges to the 2020 elections, a federal judge in Wisconsin on Saturday joined the chorus of rulings against Trump in his effort to use the courts to invalidate Biden’s victory.

“This Court has allowed plaintiff the chance to make his case and he has lost on the merits,” wrote U.S. District Court Judge Brett H. Ludwig, a Trump appointee. Ludwig noted that the president had asked “that the Rule of Law be followed,” and he declared in response: “It has been.”

The ruling comes just one day after the U.S. Supreme Court refused to consider an election challenge brought by the Texas attorney general contesting the way elections were run in four states, including Wisconsin. Trump had called that case “the big one,” because he thought it held the best hopes for him of re-litigating the 2020 contest in court.

This latest ruling marks nearly 50 losses for the president  in cases brought by him and his supporters since election day. In Wisconsin, where Biden won by more than 20,000 votes, Trump asked for 221,000 absentee and mail-in ballots to be excluded on the grounds they were collected in ways not laid out by the state legislature. And the president argued that the legislature should be afforded the chance to select an alternate slate of electors.

Ludwig’s 23-page opinion gave wide latitude to Trump -- finding that the president had standing to file his election challenge and was not too late to raise his concerns about the way the election was conducted. But the outcome of the case was the same as rulings in other battleground states -- that Biden’s victory was attained legally and should not be thrown to a legislature to upend.

The president, Ludwig wrote, “has not proved” that state election officials violated his rights. “To the contrary, the record shows Wisconsin’s Presidential Electors are being determined in the very manner directed by the Legislature, as required by Article II, Section 1 of the Constitution.”

Ludwig further noted that if he followed the demands set out in Trump’s lawsuit, “any disappointed loser in a Presidential election, able to hire a team of clever lawyers, could flag claimed deviations from the election rules and cast doubt on the election results. This would risk turning every Presidential election into a federal court lawsuit over the Electors Clause.”

The Trump campaign has not yet responded to requests for comment.

At the moment the federal ruling was handed down, the Wisconsin Supreme Court was hearing arguments on a separate challenge to a recount of votes in the state, which had failed in a lower court.
