Bachmann is not relevant here. He was stating why he signed the Gardasil executive order. He denied it was because he was lobbied by Merck, and told a story of who did lobby him. But this cancer patient could not have been the reason he acted as he had, since she met him after he had acted.
She interjected herself, so she is relevant. And he didnt deny that Merck lobbied him. He didnt address it. He brought up the woman who lobbied him because he was going to bring her up no matter what. But he didnt lie.
