JACKSON, Miss. — Authorities say a conservative Mississippi blogger went into a nursing home, photographed the bedridden wife of U.S. Sen. Thad Cochran without permission and posted an image online as part of a video.

Rose Cochran, 72, has lived at St. Catherine’s Village since 2000 and has dementia.

Clayton Thomas Kelly, 28, of Pearl was arrested Friday and charged with a felony, exploitation of a vulnerable adult, police said. Kelly remained in the Madison County Detention Center on Saturday on $100,000 bond.

Cochran attorney Don Clark said an unauthorized photo of Rose Cochran was taken in her nursing home room, near her bedside, and it was posted briefly online as part of a video. Police Sgt. Robert Sanders said the video is no longer online.

Cochran’s June 3 Republican primary challenger, state Sen. Chris McDaniel, said his campaign has no connection to Kelly.

“I’ve reached out to Senator Cochran directly to express my abhorrence for the reprehensible actions of this individual,” McDaniel said in a statement Saturday. “This criminal act is deeply offensive and my team and I categorically reject such appalling behavior.”

Kelly’s Facebook page includes a photo of Kelly with McDaniel at a campaign meet-and-greet event. Kelly has a blog that includes a post that says: “When it comes to Republicans with a bad voting record, you can’t get any worse than Thad Cochran. Thad should represent the ‘Controlled Opposition’ Wing of the Republicans more than John McCain or Lindsey Graham.”

Cochran, 76, was elected to the Senate in 1978 after six years in the House. He is a former chairman of the Senate Appropriations Committee.
