GOP Sen. John Barrasso said Thursday on FOX News that allegations about Gen. Mark Milley's behavior detailed in an upcoming book on the final days of the Trump presidency would be "very problematic" if true.
"General Milley is going to have to testify under oath about what happened because these allegations are very serious. It is the civilians that oversee the military and it is in the constitution. We have to verify all of these and get to the bottom of this. And if they are true, General Milley has to go," he said.
"Communication isn't the concern. It is the content of that communication and if the general is going outside of the chain of command, then it is absolutely off-limits and if these things are verified, then he would need to go. Whether it is a resignation or a firing from the president or if criminal charges would be brought him, that would be determined. "
