Joe Biden Delivers

This is what we've been waiting for:

Biden had an awkward moment during a rally in Columbia, Mo., Tuesday. At the start of his remarks, he pointed out several state lawmakers in the audience for praise. When he got to Chuck Graham, a state senator from Green Meadows, Biden urged the lawmaker to "stand up Chuck, let 'em see ya."

But Graham, who is in a wheelchair, can't stand up - a fact Biden quickly picked up on.

"God love ya, what am I talking about," Biden said. "You can tell I'm new," he quipped, asking the audience to stand up for Graham instead.

"It happens all the time," Graham told Politico after the rally. He called Biden very gracious for coming over to him once he realized his mistake.

"It still happens to me after 12 years" in state politics, said Graham. "It doesn't bother me a bit."
