In an ongoing House Rules Committee hearing about the resolution to call on Vice President Mike Pence to invoke the 25th Amendment, Democrats are pushing back on GOP Rep. Jim Jordan of Ohio for continuing to suggest the 2020 election should be investigated for fraud.

When Committee Chair James McGovern, D-Mass., asked Jordan if he will concede that the election was not stolen, Jordan repeated Biden was the president-elect but wouldn't say if, in his view, Biden won fairly.

"He won the election because the way the process works is the last chance to object is Jan. 6, and the objection didn't prevail," Jordan said.

"If we want to talk about healing, we have to talk about truth," McGovern interjected in a contentious exchange. "And if we want to talk about healing, we have to deal with the issue of accountability."

Rep. Jamie Raskin, D-Md., who authored the resolution, at one point asked if there's anything Trump could possibly do that would cause Jim Jordan to not defend him.

"Even after a mob of violent insurrectionists staged a gallows outside of the Congress and chanted, 'Hang Mike Pence,' even though they tried to force Mike Pence not to do his job, even after five people are dead, we continue to hear these lies and slurs about the 2020 presidential election," Raskin said.

Rep. Ed Perlmutter, D-Colo, also directly asked Jordan, "Joe Biden won the election, yes or no?"

"Yes, he won. But there are serious problems with this election that deserve an investigation," Jordan said, continuing to air his grievances until Perlmutter interrupted, "I asked you a yes or no question. Please! We're trying to bring this nation back together. Jim, please!"

Jordan, a Trump loyalist, received the Presidential Medal of Freedom from Trump in a closed ceremony at the White House on Monday.

House leadership is currently meeting with the United States Capitol Police's acting police chief and the new House Sergeant at Arms to discuss security concerns and threats related to Capitol Hill following the Jan. 6 riot, a top Democratic House aide tells ABC News.

The aide said House Speaker Nancy Pelosi called the meeting, which includes Rep. Zoe Lofgren, D-Calif., who chairs the House Administration Committee overseeing House security, and Rep. Rosa DeLauro, D-Conn., among others in leadership.

Later Tuesday, there will be an all-senators briefing on inauguration security. The briefing will not occur in person.

Senate Minority Leader Chuck Schumer notified senators of the briefing, which will include representatives from the Secret Service, Department of Defense and Department of Homeland Security, according to a Senate source.

Tuesday's meetings come after Democratic offices distributed a memo to colleagues on how lawmakers can be reimbursed for purchasing bulletproof vests and hiring security.

The House Rules Committee began meeting at 11 a.m. Tuesday to take up the rules governing floor debate for a resolution pressing Vice President Mike Pence to use the 25th Amendment and force Trump out of office.

"It is absolutely critical for us to make clear that this was a dereliction of presidential duties," said Rep. Jamie Raskin, D-Md., one of the resolution's co-sponsors. "The president is not even minimally discharging the basic duties of his office."

A vote on the resolution is expected around 7:30 p.m., according to House Majority Leader Steny Hoyer’s office.

Democrats will give Pence "24 hours after passage" to respond and mobilize the Cabinet to remove Trump, said House Speaker Nancy Pelosi in a statement Monday, otherwise the House will move forward with an impeachment vote as early as Wednesday, setting up Trump to be the first president in U.S. history impeached twice.

The House Rules Committee is expected to take up rules governing floor debate for the impeachment resolution -- which charges Trump with inciting an insurrection -- later in the day.

The president appeared before the press for the first time since last Wednesday -- the day his supporters stormed the Capitol following his remarks at a rally calling on them to march to the building -- when he departed the White House for Alamo, Texas, on Tuesday morning. He took the opportunity to criticize efforts to remove him from office.

"As far as this is concerned, we want no violence -- never violence," Trump said outside the White House. "On the impeachment, it's really a continuation of the greatest witch hunt in the history of politics. It's ridiculous. It's absolutely ridiculous. This impeachment is causing tremendous anger, and you're doing it, and it's really a terrible thing that they're doing."

"For Nancy Pelosi and Chuck Schumer to continue on this path, I think it's causing tremendous danger to our country, and it's causing tremendous anger," Trump added. "I want no violence."

Trump is expected to hold an event related to the souther border later this afternoon. Before addressing impeachment, he said the wall has made a "tremendous difference" in stopping illegal immigration.

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.
