Donald Trump will speak publicly on Tuesday after being arraigned in New York on charges relating to hush money paid to a porn star before the 2016 election.
The 76-year-old is expected to be arraigned, fingerprinted and photographed at a Manhattan courthouse as he becomes the first former US president to face criminal charges.
Police have erected metal barriers around Trump Tower and blocked roads near Manhattan Criminal Courthouse as they brace for potential protests.
Here’s what you need to know.
Will there be a Trump mugshot?
The former president is expected to fly to New York on Monday and stay at his Trump Tower in Manhattan overnight ahead of his planned arraignment Tuesday.
An arraignment is a formal reading of criminal charges in the presence of the defendant.
He is expected to report to the courthouse early Tuesday morning, where he will be fingerprinted and have a mug shot taken.
These are standard parts of the booking procedure. New York law generally bars the release of mugshots, however Mr Trump’s could be leaked.
Investigators will complete arrest paperwork and check to see if he has any outstanding criminal charges or warrants.
Once the booking is complete, Mr Trump will appear before a judge for an afternoon arraignment.
That will take place in the same Manhattan courtroom where his company was tried and convicted of tax fraud in December.
Officials from the Secret Service and the New York Police Department toured the courthouse Friday and met about security plans.
What are the charges?
A grand jury in Manhattan voted to indict Mr Trump after hearing months of evidence about a $130,000 payment to then porn star Stormy Daniels in the last days of the 2016 election campaign.
The exact details of the charges are not yet known. CNN reported Mr Trump faced more than 30 counts related to business fraud, citing anonymous sources familiar with the case, although this has not been officially confirmed.
Prosecutors have scrutinised money paid to Ms Daniels, who claimed to have had a sexual encounter with Mr Trump in 2006.
The Manhattan inquiry is investigating whether his company falsified business records over the $130,000 (£106,000) made to Ms Daniels – whose real name is Stephanie Clifford – by Mr Trump’s former lawyer Michael Cohen.
Mr Cohen, who has given evidence to the grand jury in recent weeks, pleaded guilty to violating campaign finance laws, among other charges related to the case, in 2018.
He said he was directed by Mr Trump to arrange payments totaling $280,000 (£229,000) to Ms Daniels, as well as to Playboy model Karen McDougal, to buy their silence. Mr Cohen was sentenced to three years in prison and has since been released.
Prosecutors have not said whether they intend to seek prison time in the event of a conviction for Mr Trump.
