Federal law enforcement officials have advised police agencies in state capitals to increase their security posture at statehouses around the country following the riot at the US Capitol, law enforcement sources told ABC News.

The concern, the sources said, is an emboldened right-wing that considered Wednesday a success and may next turn to locations in closer to home.

Like the U.S. Capitol, statehouses are often backdrops for demonstrations that law enforcement officials now fear could turn violent.

“The safety of the Massachusetts State House, its employees and its neighbors is of utmost importance. As we witness the events in Washington, DC and across the nation, we are aware of the need to ensure the safety of this building and those who work within it. We continually assess our security needs and will adjust as necessary,” said Massachusetts Gov. Charlie Baker, Senate President Karen Spilka and House Speaker Ronald Mariano in a joint statement.

Across the country in Washington state, Gov. Jay Inslee activated the National Guard to patrol the Capitol Campus when the state legislature convenes Monday.

“As legislators begin their work on behalf of the people of the state of Washington, we must do whatever we can to ensure that they can do that work without fear, intimidation or harassment. The actions we saw in both Washington, D.C. and Olympia earlier this week were completely unacceptable and will not be repeated in our state capital again,” Inslee said.

Security was also increased around the statehouse in Maryland, Gov. Larry Hogan said.

“Maryland State Police as well as Maryland Capitol Police, some of which you see around here, have increased security around the Maryland State House complex, since there’s been a number of incidents at state capitols and governor’s mansions around the country,” Hogan said.

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.

Trump has been quiet Saturday after Twitter announced Friday evening that it had permanently suspended the president's account.

"After close review of recent Tweets from the @realDonaldTrump account and the context around them -- specifically how they are being received and interpreted on and off Twitter -- we have permanently suspended the account due to the risk of further incitement of violence," Twitter wrote in a statement.

Trump's final tweet said he would not be attending Biden's inauguration.

After Twitter's announcement, Politico reported that the president went "ballistic" and “[scrambled] to figure out what his options [were].”

Hours after his suspension, Trump released a statement criticizing the ban and teasing a possible new platform.

"I predicted this would happen," he wrote in part. "We have been negotiating with various other sites, and will have a big announcement soon, while we also look at the possibilities of building out our own platform in the near future. We will not be SILENCED!"

"Twitter is not about FREE SPEECH. They are all about promoting a Radical Left platform where some of the most vicious people in the world are allowed to speak freely," he added.

Trump had attempted to post the same statement on Twitter using the official @POTUS account, but the platform deleted the thread, saying users who are banned cannot post from other accounts.

Secretary of State Mike Pompeo blasted Twitter Saturday, comparing the ban of the president to something that would happen in China.

"Silencing speech is dangerous. It’s un-American. Sadly, this isn’t a new tactic of the Left. They’ve worked to silence opposing voices for years. We cannot let them silence 75M Americans. This isn’t the [Chinese Communist Party,]" he wrote on Twitter.

Former Ambassador to the United Nations Nikki Haley also took to the platform to draw a comparison to China writing, "Silencing people, not to mention the President of the US, is what happens in China not our country. #Unbelievable"

The White House announced Thursday that the president planned to spend the weekend at Camp David before notifying reporters that the trip was canceled. The president has nothing on his schedule Saturday.
