WAUWATOSA, WI (WTAQ) - Wisconsin Congressman Paul Ryan is refusing to talk about speculation he might be chosen as a vice presidential running mate for Mitt Romney. At an appearance Tuesday in Wauwatosa, Ryan was asked what it’s like to be vetted for the position. His terse response was, “Next question.” Ryan was appearing at a news conference with fellow Republican, Governor Scott Walker. Walker says he would like to see Ryan as vice president, saying the fact Ryan is being considered shows how serious Romney is about solving federal government problems. Ryan says it doesn’t help the Romney campaign to fuel speculation, so he won’t be commenting for now.
