Former Trump White House trade adviser Peter Navarro has been denied the ability to use executive privilege as a defense in court after U.S. District Judge Amit Mehta ruled that Donald Trump had not formally invoked the privilege. Navarro had been subpoenaed by the Jan. 6 House select committee in Feb. 2022 as part of its investigation into the attack on the Capitol. It is unclear what other defense Navarro may use in the case.
