House Republican Conference Chairwoman Liz Cheney (Wyo.) condemned attacks on Lt. Col. Alexander Vindman, a witness called to testify as part of the impeachment inquiry, blasting those who have questioned his patriotism on Tuesday. Cheney, the No. 3 Republican in the lower chamber, did not spell out who she was criticizing for attacks on Vindman, but her remarks followed a critical tweet by President Trump.
