MILWAUKEE — Republican Senate candidate Tommy Thompson's campaign says his son has apologized for suggesting that voters should send President Barack Obama back to Kenya.

Jason Thompson, the son of the former Wisconsin governor, was caught on camera during a Sunday brunch hosted by the Kenosha County Republican Party.

"We have the opportunity to send President Obama back to Chicago – or Kenya," said Jason Thompson, an attorney at a large Milwaukee law firm. The comment drew laughs from the crowd, with one woman joking, "We are taking donations for that Kenya trip."

The video was taken by a Democratic Party operative and posted at BuzzFeed Politics on Sunday, according to the Milwaukee Journal Sentinel.

Obama's father was Kenyan, but the president was born in Hawaii.

Jason Thompson, 38, has been involved in his father's efforts to win a Senate seat and has represented the candidate at some events.

"The governor has addressed this with his son, just like any father would do," the campaign said in a statement. "Jason Thompson said something he should not have, and he apologizes."

Michael Best & Friedrich, the firm where Jason Thompson works, issued a statement Monday distancing it from the comments, calling them "regrettable."

"Jason has apologized for the comment through the campaign (and to his colleagues at the law firm) and the matter is being dealt with between father and son," the statement said.

Democratic Rep. Tammy Baldwin is running against Thompson. Her campaign's spokesman, John Kraus, said Monday that the Thompson campaign is becoming increasingly desperate and dishonest.

The candidate himself "has not apologized for these comments, nor has he disavowed them," Kraus wrote. "Thompson needs to start taking responsibility for what his campaign says and does."

Republican National Committee Chairman Reince Priebus and Wisconsin Republican Party Chairman Brad Courtney also spoke at the Kenosha event.

Priebus issued a statement Monday, saying he agreed with the elder Thompson. "The comment was out of line and his son rightfully apologized," he said.

Allen West (R-Fla.). West warned constituents at a Tuesday town hall event that he's "heard" that dozens of his Democratic colleagues in the House are members of the Communist Party, the <em>Palm Beach Post</em> <a href=" http://www.palmbeachpost.com/news/state/allen-west-hears-cheers-jeers-at-town-hall-2295766.html?cxtype=rss_news" target="_hplink">reported</a>.

"The Congressman was referring to the 76 members of the Congressional Progressive Caucus. The Communist Party has publicly referred to the Progressive Caucus as its allies. The Progressive Caucus speaks for itself. These individuals certainly aren't proponents of free markets or individual economic freedom," Melvin said in a statement to The Huffington Post.

  • Welfare Prison Dorms?

    The AP <a href="http://www.huffingtonpost.com/2010/08/22/carl-paladino-backs-welfa_n_690284.html" target="_hplink">reported</a> in August of 2010 on then-New York gubernatorial candidate Carl Paladino: <blockquote>Throughout his campaign, Paladino has criticized New York's rich menu of social service benefits, which he says encourages [undocumented] immigrants and needy people to live in the state. He has promised a 20 percent reduction in the state budget and a 10 percent income tax cut if elected. Asked at the meeting how he would achieve those savings, Paladino laid out several plans that included converting underused state prisons into centers that would house welfare recipients. There, they would do work for the state - "military service, in some cases park service, in other cases public works service," he said - while prison guards would be retrained to work as counselors. "Instead of handing out the welfare checks, we'll teach people how to earn their check. We'll teach them personal hygiene ... the personal things they don't get when they come from dysfunctional homes," Paladino said. ... Paladino told The Associated Press the dormitory living would be voluntary, not mandatory, and would give welfare recipients an opportunity to take public, state-sponsored jobs far from home. "These are beautiful properties with basketball courts, bathroom facilities, toilet facilities. Many young people would love to get the hell out of cities," Paladino he said. He also defended his hygiene remarks, saying he had trained inner-city troops in the Army and knows their needs. "You have to teach them basic things - taking care of themselves, physical fitness. In their dysfunctional environment, they never learned these things," he said.</blockquote>
