"He’ll be in full attack mode, and I don’t think he’ll let any inconvenient facts get in his way," Ryan said.

The pair appeared together at a campaign rally in Virginia on Thursday night. During the appearance, Ryan debuted a new attack on Biden saying that the administration wanted to let tax cuts for the wealthy expire.

“Last night, President Obama made it very clear he’s going to raise taxes,” Ryan said. “Today, Vice President Joe BidenJoseph (Joe) Robinette BidenOvernight Tech: FCC won't delay net neutrality vote | Google pulls YouTube from Amazon devices | Biden scolds social media firms over transparency Medicaid funds shouldn't be used to subsidize state taxes on health care Biden hits social media firms over lack of transparency MORE made it even more clear. He asked himself a question. He asked if he and President Obama want a trillion-dollar tax hike, and his answer to himself was, ‘yes we do.’ Well Virginia, no we don’t.”

Biden made the remark at a campaign rally on Thursday.

“You know the phrase they always use?,” Biden said. “Obama and Biden want to raise taxes by a trillion dollars. Guess what? Yes we do, in one regard. We want to let that trillion-dollar tax cut expire so the middle class doesn’t have to bare the burden of all that money going to the super wealthy.”
