“Most people understand that Joe Biden has been debating for a long time,” said Priebus on CNN’s “State of the Union” on Sunday.

Priebus said that while Biden had been the source of numerous gaffes on the campaign trail, Republicans should be cautious. “Joe Biden has of late put his foot in his mouth in very public ways, I mean he said that the middle class was crushed under the policies of Obama and Biden and he’s said some things that were problematic,” said Priebus.

“Paul is going to do a great job, but also I think it’s very important that people understand that, people realize that Joe Biden is a gifted orator, is very good at rhetoric, is very relatable,” he added.
