Liz Cheney has denied claims that she supports gay marriage.

Cheney, the daughter of former vice president Dick Cheney, announced last month that she will be challenging Wyoming Senator Mike Enzi in the Republican primary. Dick Cheney has previously said that he supports the marriage of his daughter Mary Cheney, who is openly gay.

“I am strongly pro-life and I am not pro-gay marriage,” Cheney said in a statement posted on her website. “I believe the issue of marriage must be decided by the states, and by the people in the states, not by judges and not even by legislators, but by the people themselves.”

Cheney cited a “push poll” in which pollsters asked, “Are you aware that Liz Cheney supports abortion and aggressively promotes gay marriage?”

“I call on Senator Enzi to denounce this poll and tell the National Republican Senatorial Committee, or anyone else promoting untruths on his behalf, to stop,” Cheney said in her statement.

Enzi spokesman Coy Knobel took exception to the suggestion in an email: Enzi “would never support a push-poll, or tolerate anyone working for him who conducted one. For Liz Cheney to assert otherwise, without any proof whatsoever, shows more about her campaign than Mike Enzi's.”

Christian conservative Bryan Fischer, spokesman for the American Family Association (AFA), has previously asserted that Cheney is too pro-gay.

“In 2009, she inartfully dodged two attempts to press her to declare her position on sodomy-based marriage, which in the end means just one thing: she's for it,” Fischer wrote last month.
