If you know Priebus' history, Priebus lost touch with reality in 1988.  He hasn't found a way back since.

Believe what he says?  He's spouted a steady stream of lies since 1988. His lies have become more ludicrous by the day. Add in he's working for Trump now?  

Nothing he's going to promise is to be trusted.

Example:
Priebus said: " Trump is now going to work toward focusing 24-7 on being president of the United States," 

Ha ha ha ha ha ha ha ahaha hahahaha ha 

Example: The Trump White House will set up a legal system to avoid conflicts of interest, Priebus said.

Ha haha hahah ahahahahaha hahaha

Phhhhhhhtttt…

My bet is he's open to impeachment with the first week.
