An ex-top White House adviser has been charged with contempt of Congress for refusing to cooperate with the investigation into the US Capitol riot last year.
Peter Navarro is the second Trump aide to be arrested after refusing to comply with a legal summons issued by the congressional committee investigating the attack.

Mr. Navarro could face up to two years in prison or a fine.
He was arrested earlier in the day by FBI agents at a Washington airport while attempting to board a flight to Nashville, Tennessee.
“Who are these individuals? This isn’t America, folks “According to the report, the former economics professor stated in court. “For four years, I was a distinguished public servant!”
Outside, Mr. Navarro objected to being placed in handcuffs and leg irons while being taken into custody.
