The presidential pardon only applies to federal crimes. As NBC reported last night, it is possible for state governments to press charges in some of the alleged crimes committed by Trump’s cronies.
…Mueller is teaming up with New York Attorney General Eric Schneiderman. “One of the people familiar with progress on the case said both Mueller’s and Schneiderman’s teams have collected evidence on financial crimes, including potential money laundering,” he notes.
Trump can pardon anybody facing charges from Mueller, but not from Schneiderman.
