Judge orders Trump aides to testify before Jan. 6 grand jury.

A federal judge has ruled that some of former President Donald Trump's closest aides, including ex-chief of staff Mark Meadows, must testify before the grand jury investigating his involvement in efforts to overturn the 2020 election. The judge rejected Trump's argument that executive privilege allowed him to block testimony from former advisers. Trump is expected to appeal the sealed ruling. Legal experts say a criminal investigation usually overcomes executive privilege.
