Donald Trump is in police custody and he is being processed at the Manhattan district attorney’s office ahead of his arraignment. He is officially the first president to face criminal charges when he appears in court following his historic indictment, writes CNN.

The indictment is expected to be unsealed Tuesday, providing the first public details about the specific charges. CNN has reported Trump will face more than 30 counts related to business fraud as part of a probe into hush money payments made to an adult film actress in 2016.

Trump’s legal team has said the former president will plead not guilty and challenge the charges. The former president, who has vowed to continue his 2024 bid, is slated to fly back to Florida after the arraignment and speak tonight at Mar-a-Lago.
