Rep. Paul Ryan told reporters Friday that he is "comfortable" with how Romney's campaign is managing his role as the vice presidential nominee, after Wisconsin Gov. Scott Walker questioned in a radio interview whether the campaign was effectively using the relative newcomer.

Walker, who recently survived a recall election in Wisconsin, praised Mitt Romney for making a "bold" choice in selecting his friend and seven-term congressman from his home state.

But Walker told radio host Charlie Sykes that the Romney campaign could be using Ryan, 42, more effectively. He suggested Ryan could teach the Republican presidential nominee a thing or two.

"They not only need to use him out on the trail more effectively, they need to have more of him rub off on Mitt, because I think Mitt thinks that way but he's gotta be able to articulate that. I think he's got a compelling message, he just has to get out and tell it. I think too many people are restraining him from telling it," Walker said Friday on WTMJ Newsradio.

On Friday afternoon Ryan flew from New Orleans to Florida with his mother, Betty Ryan Douglas, and together they visited a fruit stand in Lakeland and purchased Florida-grown tangerines. Afterward a reporter asked him to weigh in on the governor's assessment of his role in the presidential campaign.

Referring to Walker, Ryan said, "Oh he's just a good backer of mine. I feel very good about it."

He said he was happy with where he was going and the events he was attending, including the contentious speech at the AARP convention.

"Look at what we're doing; we're talking to local people, going around the country, talking to local press. I'm excited about my role, and I feel very comfortable with it," Ryan said.

When pressed on whether the vice presidential hopeful feels the Romney campaign is incorporating his ideas into their overall message. He said, "I do, absolutely."

During the interview with the conservative radio host, Walker said the Republican presidential campaign could learn from his difficult recall election in Wisconsin.
