The House select committee investigating January 6, 2021, has recently interviewed former Transportation Secretary Elaine Chao and is in talks with former Education Secretary Betsy DeVos as well as former National Security Adviser Robert O’Brien, multiple sources tell CNN. Chao and DeVos, both members of former President Donald Trump’s Cabinet, resigned a day after the attack on the US Capitol and discussed invoking the 25th Amendment to remove Trump from power.
