There is growing concern in the US about threats against federal law enforcement officials after the FBI seized Donald Trump's Florida home.
The FBI and the Department of Homeland Security DHS have warned of a spike in violent threats posted online in the days since the former president's Mar-a-Lago estate was searched.
Here is what the FBI has confirmed so far.
What kind of threats are being made?
The DHS has said it sent a bulletin on Friday about the threats, but won't share it in full. Multiple US media outlets have reported on the bulletin's contents.
The bulletin said that the FBI and DHS have observed an increase in threats to federal law enforcement and other law enforcement and government officials after the FBI executed a search warrant in Palm Beach, Florida.
The memo said there was a threat to place a so-called dirty bomb in front of FBI Headquarters and issuing general calls for '' civil war and '' armed rebellion. US agencies have identified several articulated threats and calls for the targeted killing of judicial, law enforcement and government officials associated with the Palm Beach search, including the federal judge who approved the Palm Beach search warrant. The bulletin also stated that most threats were occurring online, according to news reports.
The former president and a number of his supporters in Congress have condemned the seizure of documents from his Mar-a-Lago estate accusing the FBI of being corrupt and politically motivated.
The FBI hasn't confirmed the existence of the bulletin, but said it's always concerned with threats of violence to law enforcement. Some Republicans in Congress and many conservative pundits have responded with anger at the FBI and the officials involved in the investigation of Mr Trump, and messages to their supporters claiming that the FBI would target them next.
Some Trump allies have compared the FBI to the Gestapo, while others are saying it needs to be halted, and some accused the agency of being politically motivated.
Politicians on both sides have called for calm amid increased threats of violence.
Democratic Senator Amy Klobuchar believes that Donald Trump and his supporters are inflaming the situation by attacking the integrity of law enforcement agencies.
Brian Fitzpatrick, a Republican, has called for calm, including from the former president.
The Republican representative, Michael McCaul, said that the kind of threatening language was inflammatory, saying no law enforcement should find itself in the bullseye.
Republicans have stepped up their demands for the release of an FBI affidavit showing the justification for the seizure of documents at Mr Trump's Florida residence.
After the unprecedented search last Monday, investigators were allowed to discover that Mr Trump had 11 sets of classified documents at his home, and that the Justice Department had probable cause to conduct the search based on possible Espionage Act violations.
The unsealing of such affidavits would require approval from a federal judge.
I think a releasing of the affidavit would help, at least that would confirm that there was justification for the raid, Republican Senator Mike Rounds told NBC.
The Justice Department should'show that this was not just a fishing expedition, that they had due cause to go in and to do this, that they did exhaust all other means'', Mr Rounds said.
