A national Tea Party group is going on air next week in Kansas, attacking Sen. Pat RobertsPat RobertsA guide to the committees: Senate Angst in GOP over Trump's trade agenda CNN's Acosta: 'The fix is in' on who gets to ask Trump questions MORE (R-Kan.) as he heads into the final week of his primary fight with radiologist Milton Wolf.
Roberts is heavily favored in his primary fight with Wolf, but his supporters remain wary of a possible last-minute influx of outside spending from conservative groups.
However, many of the national conservative groups, including Citizens Fund, have little to spend coming out of a costly and expensive primary fight in Mississippi, which they lost.
And Wolf’s campaign suffered another setback this week, with the revelation that a state ethics board has launched an investigation into Facebook postings of his in which he gave off-color commentary on X-rays, which he’s claimed broke no rules and did not belong to his patients.
The initial report outlining those posts stalled Wolf’s campaign earlier this year, and now the investigation has given the Roberts campaign further fodder for attacks. It launched a new television ad Friday highlighting the investigation and declaring Wolf “unfit, not trusted, not right for Kansas.”
