Don’t worry - there will be plenty of time to investigate that in 2023. We will subpoena her chat messages, text messages, e-mail, and phone records and those of her staff, her family, the family of her staff. We will subpoena all records of her communications with Gen. Milley, seeking to interrupt the chain of command. Magically, all of that will leak directly to the internet. Before she testifies under oath.
You will need different Republicans than the 145 that voted for Liz Cheney in Feb of 2021 for any of that to happen.
