Former Trump adviser Stephen Miller to testify before January 6 committee

His cooperation is a blow to Trump's efforts to shield information about his movements on the day of the insurrection

Stephen Miller, Donald Trump's former top adviser, will give testimony to the January 6 committee today, according to a source familiar with the matter.

The reported cooperation of Miller is further evidence that the House investigation into the Capitol riot is lapping at the doors of the Trump Oval Office, after the former president's daughter and son-in-law, Ivanka Trump and Jared Kushner, both former senior White House advisers, gave their own testimony in recent weeks.
