"On Wednesday, several current and former defense officials rejected the criticism that Milley was acting in secret or out of authority, saying that the calls were conducted under protocols similar to other high-level engagements by the Joint Chiefs chairman and in consultation with the Defense Department.
More than a dozen people were on both videoconference calls Milley held with Li, i
ncluding a representative from the State Department, a defense official had told CNN. The read-out and notes from the calls were shared with the intelligence community and the interagency, the official said."
In other words, is it shocking that the republicans that rail against an investigation into an actual attack on the capitol are so outraged about a call that follows standard protocols in the army? With the current state of the republican party, sadly, not.
