(CNN) – President Barack Obama’s second cousin (once removed) will challenge Sen. Pat Roberts, R-Kansas, for his seat in a GOP primary next year.
Republican Milton Wolf, a board-certified radiologist and conservative activist, announced his plans Tuesday night at an event in Overland Park, Kansas. His campaign marks his first attempt to run for public office.

“I’m here today to fight for our Constitution and the divinely-inspired American idea of individual liberty, limited government and free enterprise,” he said, according to a news release announcing his campaign. “I’m here today to reclaim the American Dream for all Kansans and all Americans.”
While Wolf’s name has never appeared on a ballot, he has become known nationally as a staunch opponent against Obamacare and regularly contributes to right-leaning news outlets.
His mother was a first cousin of Obama’s maternal grandmother, he wrote on his website, and Wolf’s mother and Obama’s mother were childhood friends in Wichita, Kansas.
“I’m enormously proud that America has elected our first black president and I’m also enormously proud to call this president family," Wolf, 42, wrote. "Still, I have profound differences in opinion with Barack.”
Roberts won re-election in 2008 with 60% in the reliably red state. The incumbent senator has already begun preparing for his re-election bit to a fourth term, and he had $1.5 million in the bank as of June 30.
The senator is the latest Republican to get a primary challenger for the 2014 midterm elections. Senate Minority Leader Mitch McConnell of Kentucky, Sen. Lamar Alexander or Tennessee, Sen. Lindsey Graham of South Carolina, and Sen. Mike Enzi of Wyoming are among those who will face opponents in their respective GOP primaries.
Roberts' campaign pointed to the senator's credentials as a fiscal, anti-abortion conservative with an A rating from the National Rifle Association.
"Kansans know Senator Pat Roberts as a tough, tested and trusted conservative who works hard for Kansas," Leroy Towns, Robert's executive campaign manager, said in a statement, adding Wolf will "have many questions to answer regarding his position on major issues."
"Pat Roberts always welcomes the chance to discuss important issues we face and he takes every election seriously," he added.
