Wisconsin Gov. Scott Walker (R) said in an interview broadcast Sunday that the 2016 GOP presidential ticket should be made up of governors, not members of Congress.

"I think it's got to be an outsider," Walker said on ABC's "This Week With George Stepahnopoulos." "I think both the presidential and the vice presidential nominees should either be a former or current governor, people who have done successful things in their states, who've taken on big reforms, who are ready to move America forward."
