DePape was watching him:
"Paul Pelosi told the 911 operator that he didn't need police, fire or medical assistance in an attempt to "defuse the situation" as DePape was watching him on the phone, the document states. He then asked where the Capitol Police were because "they are usually at the house protecting his wife.""
Again, this could all be cleared up if they'd just release the entire 911 recording along with security footage and body cams.
