Milton Wolf says the medical board has determined he committed no wrongdoing by posting the images on Facebook.

Wolf, one of his attorneys and a former campaign staffer issued email statements Monday saying that the Board of Healing Arts had closed an investigation started last year.

The board’s executive director said in a statement that its investigations are confidential.

Wolf is a Leawood radiologist who had tea party backing in challenging Roberts in last year’s Republican primary. Roberts won the four-candidate race with 48 percent of the vote. Wolf received nearly 41 percent.
