The brother of GOP Senate candidate Kevin Nicholson reportedly donated the maximum amount he could to the Wisconsin Democrat that Nicholson is hoping to unseat.

Nicholson's brother, Scott, donated the maximum $2,700 to Sen.

The report comes after CNN reported earlier this month that Nicholson's parents also maxed out their campaign contributions to Baldwin, each giving $2,700 to her campaign.

Kevin Nicholson said in a statement he has a "different worldview" than his parents, noting it is "not surprising" they would support a candidate like Baldwin.

“I’m a conservative today not because I was born one, but because of the experience I earned as a Marine in combat, my experience as a husband and father, my choice to be a Christian, the schools I chose to attend and the decision to pursue the career that I have," he said.

Kevin Nicholson announced in July he would be running in the GOP primary for Baldwin's seat.

He faced questions about his political views over his past position as president of the College Democrats of America and his speech at the Democratic National Convention in 2000.

He said last year that he permanently changed parties after he served in Iraq in 2007.
