Republican U.S. Senate candidate J.D. Hayworth's campaign is defending his role as a pitchman three years ago for a Florida company that consumer advocates have accused of airing misleading ads.

The Federal Election Commission has dismissed a complaint alleging that J.D. Hayworth improperly used his former Phoenix-area radio show in his bid to unseat Arizona Sen. John McCain.

A now-disbarred Florida lawyer who admitted to orchestrating a huge Ponzi scheme gave more than $180,000 to Arizona Sen. John McCain's presidential campaign, contributions that McCain's Senate rival is now making an issue in their competitive primary.

John McCain's re-election campaign has released its second set of television and radio ads attacking the Arizona senator's primary opponent for his ties to Washington.

A man who recently served as an adviser to John McCain's rival and once helped launch the Minuteman border watch movement has been accused by his estranged wife of threatening to kill their family and any police who try to protect them.

John McCain is calling in former Massachusetts Gov. Mitt Romney on Friday.
