Pence's former chief of staff calls Democrats' discussions about invoking the 25th Amendment in wake of Capitol riot a "publicity stunt"

Marc Short, who was former Vice President Pence's chief of staff on Jan. 6, 2021, accompanied Pence to the Capitol — and then to a secure location as hordes of Trump supporters overran the building.

During the 187 minutes of rioting, Short said he talked to only one person in the White House. 

"The only conversation I had was with Mark Meadows during those several hours in which we were — had been evacuated and were down in the loading dock underneath the Capitol," Short told CBS News' Catherine Herridge in an interview Friday.
