Florida authorities say on Friday night they arrested one of the alleged Capitol rioters who was seen in a viral photograph carrying Speaker Nancy Pelosi’s lectern through the halls.

Adam Johnson, 36, of Parrish, Florida, is being held in Pinellas County Jail and charges are pending after federal marshals picked him up, according to arrest records.

Army Secretary Ryan McCarthy said Friday the Army will soon determine whether to allow Guardsmen to be armed for the inauguration based on a review of threat intelligence.

"We'll be looking at the intelligence and make a determination over the next day or so," McCarthy told the Associated Press. "It's just going to require us to get better intel, and then we'll have to make a risk assessment."

"The Secretary of the Army, in concert with Federal and Metropolitan leadership and D.C. National Guard continue to assess the security environment in the District of Columbia," an Army official told ABC News.

"As part of the standard mission analysis, we evaluate mission requirements based on requests, and it can include looking into the force posture level and the standing rules for the use of force. The Army is a planning organization and this a standard part of mission analysis," the official added.

After an hours-long phone call earlier Friday with the entire Democratic caucus, House Speaker Nancy Pelosi in a new statement is walking a fine line on next steps and remaining noncommittal on moving forward with impeachment.

Pelosi said it's still Democrats' hope that Trump will "immediately resign."

"But if he does not, I have instructed the Rules Committee to be prepared to move forward with Congressman Jamie Raskin’s 25th Amendment legislation and a motion for impeachment. Accordingly, the House will preserve every option – including the 25th Amendment, a motion to impeach or a privileged resolution for impeachment," she said in the statement.

This comes after nearly 160 Democrats have signed on to legislation in support of a single article of impeachment against the president -- which it is expected that they still plan to introduce as early as Monday -- but Pelosi does not definitively say she will support it or that the chamber will move forward with impeachment.

White House deputy press secretary Judd Deere has issued a statement in response to movement on Capitol Hill to impeach Trump for a second time.

“As President Trump said yesterday, this is a time for healing and unity as one Nation. A politically motivated impeachment against a President, who has done a great job, with 12 days remaining in his term will only serve to further divide our great country," the statement read.
