Cummings took the witness stand in the trial of Oath Keepers founder Stewart Rhodes and four co-defendants - Jessica Watkins, Thomas Caldwell, Kenneth Harrelson and Kelly Meggs. The five are accused of conspiring to try to keep Republican President Donald Trump in power after he had lost the 2020 election. A pro-Trump mob charged into the U.S. Capitol on Jan. 6 and violently attacked police, but failed to prevent lawmakers from certifying Biden's victory. Prosecutors have said some of the Oath Keepers were among the Trump supporters who stormed the Capitol building after he gave a speech repeating his false claims that the election had been stolen from him through widespread voting fraud. The government also alleges the Oath Keepers organized a so-called "quick reaction force" of armed members who were waiting across the Potomac River in Virginia if called upon.
