NASHVILLE (AP) - Carrie Underwood is not a bandwagon person. Underwood says anyone who knows her knows she doesn't weigh in on anything unless she knows the full story, and she does her own research. Recently Underwood tweeted her opposition to Tennessee's "Ag Gag" bill, that would have impacted investigations into animal abuse on farms. Underwood was the only celebrity that Tennessee Governor Bill Haslam consulted before he vetoed the bill. Underwood says she respects that he wanted to hear everybody's point of view. Underwood says she mostly gets positive comments on what she tweets, but when there's a negative one, she says, "I enjoy blocking that person."
