Former Trump adviser Peter Navarro failed to prove that former President Trump invoked executive privilege to block him from testifying before the House Jan. 6 committee, a federal judge ruled. Navarro faces contempt-of-Congress charges for refusing to cooperate with the committee's investigation into the Capitol attack. Navarro had claimed that Trump asserted privilege during a February 2022 phone call, where Trump supposedly told Navarro not to cooperate with the panel. However, the judge ruled that Navarro provided no specific evidence to support his claim. The judge also noted that Trump never formally invoked privilege and declined to corroborate Navarro's assertions. The ruling paves the way for Navarro's trial to begin next week. If convicted, Navarro could face penalties, including fines and imprisonment. The decision raises questions about the extent to which executive privilege can shield individuals from testifying before congressional committees.
