(CNN) - Gov. Scott Walker said that fellow Wisconsinite Rep. Paul Ryan is the exception the his ideal Republican 2016 presidential candidate being from outside the Washington beltway.
Walker, a potential 2016 hopeful himself, recently told ABC that his ideal standard bearer for the GOP in the next presidential election would be an "outsider" and "former or current governor."
Walker told CNN's Piers Morgan Wednesday that, in a cast of likely 2016 contenders - including Sens. Rand Paul of Kentucky and Ted Cruz of Texas - Ryan is the exception.
"I think most people, Republican, Democrat alike, looking at Washington would like to see some outsiders come in and shake things up," Walker said, appearing on “Piers Morgan Tonight.”
"One of the few exceptions on that list probably would be someone like Paul Ryan who I know, first hand, has been a true reformer. He's from Wisconsin, but I've seen, broader than that, he's one of the few people that has the courage to take on Washington."
Walker continued: "And the other folks are good, decent people, but really, reform is happening in the states and that's why I made the point I made."
Ryan, the former Republican vice presidential nominee and chairman of the House Budget Committee, gave a flat "no" when asked at an event in Washington if the next Republican presidential nominee needs to be a governor.
"The resume is not as important to me as the person, as the quality of their ideas, as their track record of reform," Ryan said on Tuesday.
Walker, whose book "Unintimidated: A Governor's Story and a Nation's Challenge" was released earlier this week, survived a recall effort in his state last year, propelling him into the national GOP spotlight.
Walker hasn't closed any doors on a possible presidential bid, refusing to commit to serving out a second term as governor and having already made visits to key presidential primary states Iowa and South Carolina this year.
In last year's presidential election, Wisconsin backed President Barack Obama, who won 53% of the vote to Republican nominee Mitt Romney's 46%.
