President Donald Trump should not be exempt from facing civil litigation during his time in the White House, say a group of law professors seeking to be heard in the New York attorney general’s suit over alleged illegality in the Trump Foundation.

The argument was posed in a proposed brief sent to Manhattan Supreme Court Justice Saliann Scarpulla. The professors signing on to the document argued two decades ago in the U.S. Supreme Court case Clinton v. Jones, which opened the door to a sexual harassment case against President Bill Clinton in federal court.
