Martin, a fringe candidate who pushes the idea that President Obama is a Muslim and even sued the state of Hawaii to produce a ribbon copy of Obama’s birth certificate, has a history of salacious allegations and frivolous lawsuits.
His advertisement asserts that there’s “solid rumor that Mark Kirk is a homosexual” and that he’s part of the "Republican Party homosexual club."
Martin, who has twice run for president of the US, says Kirk should come clean about these accusations.
Kirk’s campaign responded saying: "The ad is not true and is demeaning to the political process," according to a statement given to WBBM 780. "The people of Illinois deserve better."
