I am new here, but maybe Kerry and Bush both had to wear ear peices for security reasons.
Does anyone recall who Bush was talking to when he said "Let me finish" during one of his answers? I went to a link someone posted on here earlier, and it claimed that Bush was using an earpiece and said Let me finish, meaning he may have been listening to someone on the other end. I don't believe that, but wanted to know if someone saw who he was talking to.
