A federal judge rejected former President Donald Trump's executive privilege claims and ordered former top aides, including Mark Meadows, to testify before a federal grand jury investigating Trump's efforts to subvert the 2020 election leading up to the Jan. 6 riot at the U.S. Capitol.

Meadows, a former White House chief of staff, was subpoenaed along with other former ranking aides by special counsel Jack Smith for testimony and records pertaining to his investigation, multiple sources familiar with the matter said.
