A GOP congressional candidate for 2014 appears to have a wild side.

Stewart Mills of Minnesota is seen in newly released photos hitting a beer bong, and licking a woman. 

In photos obtained by Minneapolis’s City Pages, Mills is seen chugging beer through a funnel. A Democratic source leaked the photos, according to the report. 

His wife originally posted the two beer bong photos to Facebook in February 2009, but they were deleted after Mills launched his congressional campaign this year.

Another photo in the report shows the candidate at a 2008 Christmas party licking the lips of an unidentified woman. 

Mills, 41, released a statement after seeing the report containing the photos.

“It's no secret that in the past I've let my hair down to have fun with family and friends. My wife and I have had many lighthearted moments in our lives but right now I am focused on my Congressional campaign and the disastrous effects of our overreaching government and sky high unemployment in the north eastern Minnesota,” he said to City Pages.
