Capitol Police warn lawmakers to be on alert for 'demonstration activity'

US Capitol Police and the Senate Sergeant-at-Arms put members of Congress on notice Friday for anticipated demonstrations around the country related to former President Trump's indictment. 

'While law enforcement is not tracking any specific, credible threats against the Capitol or state offices, there is potential for demonstration activity,' the law enforcement agencies wrote in a note to Senate staff. 

In anticipation, Capitol Police will boost its presence around Capitol Hill and continue to monitor potential impacts. 

Anti-Trump protesters have gathered in force outside Trump Tower in Manhattan to celebrate the indictment. They held up protest signs that read 'lock him up', a play on his supporters' old chants about Hillary Clinton. 

Stormy Daniels has broken her silence following the decision, which could see the former president potentially facing time behind bars

Protesters have been gathering for weeks but were out in force today outside Trump Tower following the bombshell grand jury indictment 

Supporters of former President Trump also gathered outside of his Mar-a-Lago residence in Florida.

The indictment against him signals the first time a US president has ever been criminally charged. Trump and his attorneys say it's a political witch hunt designed to hurt his chances in the 2024 election.

At least one House member - Rep. Marjorie Taylor Greene - has said she will be in New York City on Tuesday to protest the indictment and support the former president. 

The 76-year-old ex-president has been told he has to turn himself in on Tuesday or face arrest and extradition to New York.

It is unclear exactly what charges the former president will be facing, but it is understood to be in relation to the money paid to porn star Stormy Daniels and another woman.

The exact charges against Trump will be known when the indictment is unsealed, which is expected to happen next week.

They are believed to be in relation to the 2016 payment of $130,000 from his former attorney Michael Cohen to Daniels, who claims to have slept with Trump in 2005.

Trump maintains his innocence, insisting he had nothing to do with it.

Trump has already warned last week there could be 'death and destruction' over the indictment as he called Alvin Bragg a 'degenerate psychopath.' 

'What kind of person can charge another person, in this case a former President of the United States, who got more votes than any sitting President in history, and leading candidate (by far!) for the Republican Party nomination, with a Crime, when it is known by all that NO Crime has been committed, & also known that potential death & destruction in such a false charge could be catastrophic for our Country?'
