President Trump on Wednesday awarded the National Medal of Arts to five people, including country singers Toby Keith and Ricky Skaggs, and the National Humanities Medal to two people and a museum, the White House said Thursday.

Trump awarded the medals as the House voted to impeach him.

Keith is a supporter of Trump’s who performed for the then-incoming president at a 2017 inauguration-eve “Make America Great Again Welcome Celebration and Concert” at the Lincoln Memorial. Skaggs is also a Trump supporter who endorsed him in 2016.

One of the humanities medal recipients, Kay Coles James, is the president of the conservative Heritage Foundation.

The museum that received the humanities award was the National World War II Museum in New Orleans.

Director of the White House Office of Trade and Manufacturing Policy Peter Navarro, in an interview with Fox Business Thursday, blasted the House's impeachment vote as a "travesty" and blamed the Democratic Party for the country's violence.

"The Democratic Party did violence to this country by attacking a president, who I believe was legally elected on Nov. 3," Navarro said. "I would say to these people on Capitol Hill, knock it off, stop this. Let the man leave peacefully with his dignity."

The false and unsubstantiated belief that the presidential election was stolen from Trump played a large role in driving some of his supporters to storm the U.S. Capitol last week in a siege that left at least five people dead and Trump impeached for a second time.

Navarro went on to predict if the election were held again "today," Trump would be elected, and added, "If he runs in 2024, he will be elected then."

There is a preliminary plan to close the entire National Mall to the public for Inauguration Day amid security concerns, ABC News has confirmed.

The Washington Post was the first to report on the development, but The National Park Service has said it will make an announcement on the Mall following ongoing discussions with the Secret Service, the Biden Inaugural team and D.C. Mayor Muriel Bowser.

Traditionally, members of the public gather on the National Mall -- bookended by the Capitol building and Lincoln Memorial -- for viewing of the inauguration on large jumbotrons.

But the Mall's potential closure comes in the wake of a violent seige on the U.S. Capitol building last week, which left at least five people dead, and amid heightened security concerns regarding armed protests being planned ahead of Biden's inauguration on Jan. 20.

Security preparations for next week have already increased with up to 20,000 National Guard troops authorized to provide security at the Capitol and around Washington, D.C., for next week's ceremony, according to a Defense Department official.

Bowser has already warned visitors to stay away from the District for the inauguration due to threats of both the coronavirus pandemic and of violence.

Editor’s Note: A previous version of this post reported that the entire National Mall would be closed to the public for Inauguration Day amid security concerns. The text has been updated to reflect the fact that the closure is only a preliminary plan.

Arizona Gov. Doug Ducey, a Republican, has announced he will attend Biden’s inauguration after weeks of attacks from Trump for signing the certification of Arizona's election results affirming Biden's narrow win in the state.

“It doesn't matter who you supported in the election — once the election is over, we put country before party. Never has it been more important than right now to observe these traditions for the whole world to see," Ducey said in a statement Thursday.

"I was honored to represent Arizona at the inauguration of President Trump in 2017, and I am honored to represent our state at the 59th Inaugural Ceremonies next week. President-elect Biden is assuming office at a critical time in our nation’s history, and I wish him well," he added.

The Arizona Republican Party is scheduled to meet a few days later on Jan. 23, when members will vote on censuring some apparent party foes including Ducey, Cindy McCain and former Sen. Jeff Flake, R-Ariz.

Expecting the article to pass the House later Wednesday, Speaker Nancy Pelosi is planning to send the article of impeachment over to the Senate next week, according to a source involved in the Democratic leadership deliberations.

This would leave the Senate no choice but to immediately move towards a trial. The exact timing will depend on whether Majority Leader Mitch McConnell decides to call the Senate back in session early -- which he's said he wouldn't do. Under Senate rules, the Senate cannot officially receive any message or bill or resolution from the House unless the Senate is in session, and the chamber is not scheduled to be back until Jan. 19.

But in preparation for that time, Pelosi has named nine members to serve as impeachment managers to argue the case in the Senate to remove Trump from office over his role in last week’s Capitol riot.

Rep. Jamie Raskin, D-Md., a former constitutional law professor who co-authored the article and whose family was present at the Capitol last Wednesday, one day after burying Raskin's son who took his own life, will serve as the lead impeachment manager.

The other managers -- one of rarest assignments for a House member -- are Democratic Reps. Diana DeGette, Colo., David Cicilline, R.I., Joaquin Castro, Texas, Eric Swalwell, Calif., Ted Lieu Calif., Joe Neguse, Colo., Madeleine Dean, Pa., and Del. Stacey Plaskett, Virgin Islands.

"It is their constitutional and patriotic duty to present the case for the President’s impeachment and removal. They will do so guided by their great love of country, determination to protect our democracy and loyalty to our oath to the Constitution," Pelosi said in a statement Tuesday night.

The impeachment managers are a different set from those tapped by Pelosi one year ago for Trump’s first impeachment trial -- then led by Rep. Adam Schiff, D-Calif. During that effort, managers argued the case to remove Trump for pressuring Ukraine’s president to promise to investigate Biden and his son, Hunter.
