Speaking today at an event where he received the the endorsement of the U.S. Chamber of Commerce, Tommy Thompson said he does not think his son needs to apologize publicly or to the president for joking about sending Barack Obama “back to Kenya” at a GOP fundraiser.

“He has already apologized, and that’s enough,” Thompson said at a Milwaukee news conference this afternoon. “It was an offhanded remark that somebody mentioned in the audience. If you look at the movie, he didn’t say it. Somebody in the audience said it and he repeated it, and I’ve talked to him about it and he apologized and that’s it.”

“My son feels miserable about it,” he added.

Jason Thompson spoke to a Kenosha County GOP fundraiser on Sunday when he said, “We have the opportunity to send President Obama back to Chicago … or Kenya.”
