If Trump is charged, what happens next?

Preparations appear to be underway for the unprecedented scenario that Donald Trump could become the first former president in U.S. history to be indicted.

Barricades arrived outside the criminal courthouse in Manhattan on Monday while law enforcement agencies grapple with how to protect the former president. Questions also remain as to whether Trump would be handcuffed and when he would first appear in court if he is indeed charged in a case involving a hush money payment to adult film actress Stormy Daniels.
