Republicans are pressuring Vice President Joe Biden to meet with Alvin Greene, the controversial Democratic Senate candidate in South Carolina.

The Republican National Committee (RNC) mused Friday as to why Biden, who is making a swing through South Carolina on Friday, in part to campaign, hadn't planned a meeting with Greene, his party's nominee.

"In South Carolina, Dem Senate candidate Alvin Greene has stimulus proposal of his own — will Joe Biden listen?" the RNC wrote, referring to Greene's proposal to manufacture action figures of himself to boost the economy.

Biden has the time to fundraise for Rep. John Spratt, surely he could make time for Greene," the GOP committee added.

At issue is Greene's odd candidacy. He is an unemployed military veteran who won the primary election despite never having campaigned, and his nascent candidacy has been marked by a series of bizarre moments, the latest being a rap song.

Most senior Democrats have kept a distance from Greene in the campaign, and House Majority Whip James Clyburn (D-S.C.) had suggested that he was a "plant" to disrupt the election.

The RNC noted Biden's heavy campaign role for Democrats in pushing for a meeting with Greene.
