Former President Trump’s son-in-law and senior adviser Jared Kushner gave several hours of closed-door testimony Thursday to the House committee probing the January 6 insurrection at the U.S. Capitol. His appearance by video link came as federal prosecutors broadened their investigation to include organizers of pro-Trump rallies that preceded the January 6 attack on Congress. The Justice Department is also looking into how Trump’s allies conspired to promote slates of fake electors in a bid to overturn Joe Biden’s Electoral College victory in the 2020 election.
