Sam Brownback announced Tuesday former U.S. Senator Bob Dole and Humanitarian Mary Jean Eisenhower will serve as the National Co-Chairs of his 2014 re-election campaign for governor of Kansas.

In a letter, Dole and Eisenhower said they didn’t hesitate to serve as Brownback’s National Co-Chairs.

“From years of association, we know Sam Brownback to be a good man with the right ideas and experience  continue leading our great state forward,” Dole and Eisenhower wrote. “Seeing Kansas grow and prosper is one of the great joys of our lives, and we are honored to stand with Sam Brownback.  We cherish our Kansas traditions and we are excited about its future.  We urge all Kansans to join this campaign.”

Bob Dole served Kansas in the U.S. Senate from 1969 to 1996 and in the House of Representatives from 1961 to 1969.

Mary Jean Eisenhower is the president of the Board of Directors for the People to People International, a humanitarian organization founded by her grandfather, U.S. President Dwight D. Eisenhower.

Kansans elected Brownback and Jeff Colyer, M.D. as Governor and Lt. Governor in November 2010.
