Former Rep. Tom Tancredo (R-Colo.) urged Tea Partiers this weekend to help "send [Obama] back" to Kenya.

Speaking at a rally in Greenville, S.C., on Saturday, Tancredo cited remarks Michelle Obama made earlier this month in which she called Kenya was the president's "home country."

"If his wife says Kenya is his homeland, why don't we just send him back?" Tancredo said, according to the Greenville News.

Asked about Tancredo's comments, White House press secretary Robert Gibbs dismissed them as "lunacy."

"I could probably fill the better part of my afternoons responding to the lunacy of people such as Tom Tancredo," Gibbs said.
