A federal judge hearing arguments in a potentially critical impeachment inquiry case wants to hear from lawyers for the Trump White House, the House of Representatives and from impeachment witness Charles Kupperman on Thursday after Kupperman filed a lawsuit asking the federal court to decide whether he would need to testify.
Kupperman’s House testimony had been set for Monday, but Kupperman didn’t show up, citing White House and Justice Department reasoning that he was immune from testifying because of his previous work on the National Security Council.
