A pro-Trump super PAC linked to former White House chief strategist Stephen Bannon is endorsing candidates in the Wisconsin and Arizona Republican Senate primaries.

McClatchy DC reported Monday that Great America PAC will support Marine veteran Kevin Nicholson in Wisconsin's GOP Senate primary.

"Americans are tired of the inaction from the Washington swamp and demand Senate Republicans ... get off their backsides and pass President Trump's America First Agenda," the super PAC's chief strategist, Ed Rollins, said in a statement.
