The news comes as security measures are being stepped up ahead of Inauguration Day, with federal, state and local law enforcement agencies preparing for the possibility of more violence after rioters stormed the US Capitol last week leaving five people dead, including a Capitol Police officer.
Even as federal investigators continue to track down suspects from last week's attack, the bulletin highlights concerns that the US Capitol siege was perhaps just the beginning of potentially violent actions from supporters of President Donald Trump who have been animated by his lies about a stolen election.
"Armed protests are being planned at all 50 state capitols from 16 January through at least January 20, and at the US Capitol from January 17 through January 20," the FBI bulletin states. It also suggests there are threats of an "uprising" if Trump is removed via the 25th Amendment before Inauguration Day.
"On January 8, the FBI received information on an identified group calling for others to join them in 'storming' state, local and federal government courthouses and administrative buildings in the event POTUS is removed as president prior to Inauguration Day. This identified group is also planning to 'storm' government offices including in the District of Columbia and in every state, regardless of whether the states certified electoral votes for Biden or Trump, on January 20," the bulletin adds.
The FBI is also tracking reports of "various threats to harm President-elect Biden ahead of the presidential inauguration," the bulletin states. "Additional reports indicate threats against VP-elect Harris and Speaker Pelosi."
ABC News was first to report the FBI bulletin.
The FBI said in a separate statement that its "efforts are focused on identifying, investigating, and disrupting individuals that are inciting violence and engaging in criminal activity," and that its "focus is not on peaceful protesters, but on those threatening their safety and the safety of other citizens with violence and destruction of property."
The government, meanwhile, held Continuity of Government Operations – a standard practice in the event that someone tries to disrupt the transition that took on new urgency in light of threats surrounding this year's inauguration.
According to a senior administration official, the interagency rehearsal aimed to ensure a seamless chain of command in the event of a national emergency in the days leading up to the inauguration and on that day itself. Monday's rehearsal focused heavily on "readiness in the event that somebody tries to disrupt or stop the inauguration," the official said.
The calls for new protests in Washington and states across the country have law enforcement and local officials bracing for more possible violence in the coming days.
Washington Mayor Muriel Bowser on Monday urged Americans to avoid the city during Biden's inauguration next week and to participate virtually following last week's deadly domestic terror attack on the US Capitol.
Speaking at a news conference Monday, Bowser, a Democrat, stressed that she was concerned about more violent actors potentially coming to the city in the run-up to the inauguration, saying, "If I'm scared of anything, it's for our democracy, because we have very extreme factions in our country that are armed and dangerous."
"Trumpism won't die on January 20," said Bowser, who has asked for a pre-disaster declaration for D.C. The White House said in a statement Monday night that Trump approved the emergency declaration requested by Bowser.
Security preparations were further complicated when acting Homeland Security Secretary Chad Wolf, one of the key figures coordinating the effort, resigned on Monday.
In one of his last acts, Wolf said Monday that he had instructed the US Secret Service to begin the National Special Security Event operations for Biden's Inauguration on Wednesday, instead of January 19, the day before Biden is set to be inaugurated.
