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.

The danger to the public and to law enforcement officers from explosive devices during expected upcoming protests "is substantial," the Federal Bureau of Investigation warned in a new awareness bulletin obtained by ABC News on Friday.

The document is full of photos of devices used in the last eight months against civilian and law enforcement targets during public demonstrations.

"Devices targeting infrastructure also increased following violent activity during this time period," the bulletin states.

The FBI now wants to make first responders aware of what has been deployed in the past and what they might encounter during protests linked to the presidential inauguration on Jan. 20.

"The danger posed to law enforcement officers and the general public from the all the tactics listed is substantial," the bulletin states. "If a suspicious item is reasonably believed to contain explosives, an IED, or other hazardous material, DO NOT touch, tamper with, or move the item. Only bomb disposal personal should handle any suspected devices that are located."

An internal FBI bulletin obtained by ABC News earlier this week stated that armed protests are being planned at all 50 state capitols as well as at the U.S. Capitol in Washington, least through Inauguration Day.

The warning comes after suspected pipe bombs were found last week outside both the Democratic National Committee and the Republican National Committee headquarters, just a few blocks from the Capitol where pro-Trump rioters stormed the building.
