Washington (CNN) Some of the Ricketts family in Nebraska spent millions to defeat Donald Trump. Now the most high profile Ricketts is endorsing him.

Nebraska Gov. Pete Ricketts on Friday put his support behind the presumptive Republican presidential nominee while appearing at a rally with him in Omaha, Nebraska.

"Politics is run by the people that show up ... By showing up today, you have demonstrated you want to chart a new course for our country," Ricketts told the crowd in his introductory remarks for Trump. He urged them to "get behind our nominee" to prevent likely Democratic nominee Hillary Clinton from winning the White House.

Upon taking the stage, Trump called Ricketts a "great governor."

This endorsement occurs just days after Trump became the last man standing in the Republican field for the nomination, and ahead of the state's Republican primary next Tuesday.
