BBC reported that former US President Donald Trump will be charged over hush money payments made to a porn star just before the 2016 presidential election.

The details of the case against him have not yet been released. A grand jury has voted to indict him after investigating a $130,000 pay-out to Stormy Daniels in an attempt to buy her silence over an alleged affair.

Trump, 76, denies wrongdoing. He is the first serving or former US president to face a criminal charge.

The office of Manhattan District Attorney Alvin Bragg, who has been pursuing the investigation, confirmed that it had contacted Trump’s attorney to “co-ordinate his surrender” on unspecified charges.

The ex-president lives in Florida and is expected to travel to New York City for his formal arrest and first hearing in court. Trump is expected to fly to New York on Monday and be arraigned in court on Tuesday, two sources familiar with the matter told CBS News, the BBC’s US partner. The charges in the indictment will be read to him at the hearing, which is set to last about 10-15 minutes.

The United States Secret Service – which is tasked with protecting serving and former US presidents – will be in charge of security for the court appearance.
