A former adviser to Donald Trump has revealed he has been subpoenaed to appear before a grand jury this week as part of the Justice Department’s investigation into the deadly insurrection at the US Capitol.

Peter Navarro, who was a trade adviser to then-president Mr Trump, said on Tuesday that he was served by the FBI at his Washington house last week.
