The son of U.S. Senate candidate Tommy Thompson has apologized for telling voters this fall should send President Barack Obama back "to Kenya."
Jason Thompson, the son of the former governor, made the comments Sunday during a brunch hosted by the Kenosha County Republican Party.
The video was taken by a Democratic Party operative and posted at BuzzFeed Politics Sunday.
Obama's father was Kenyan, but Obama was born in Hawaii.
In a statement, Thompson's campaign said the 38-year-old son apologized for saying something he should not have. Jason Thompson is an attorney and has represented his father's campaign at some events.
Running against Thompson is Democratic Rep. Tammy Baldwin. A Baldwin spokesman declined to comment.
