Embattled Dixie Chick Natalie Maines is addressing the controversy surrounding comments she made at a March 10 concert in which she told a London audience that, "We're ashamed the president of the United States is from Texas." She says she spoke out against Bush and war in Iraq out of frustration. "I'm not truly embarrassed that, you know, President Bush is from my state," Maines says in an interview with ABC's Diane Sawyer for Primetime Thursday (airing tonight at 10 pm/ET). "It was the wrong wording with genuine emotion and questions and concern behind it. ... Am I sorry that I asked questions and that I just don't follow? No." Am I sick to death of this story? Yes.
