My only backing for this statement are words on the campaign trails and other such things.

Pence's final speech in Grand Rapids Michigan was fire, talked about draining the swamp, and how the election was the way that they were going to do it.

Also comments like "I'd like to thank Mike Pence for the "most complex military operations in history" from the DoD and such.

Then again there's always the old adage "how do you tell when a politician is lying?"
