Liz Cheney, the eldest daughter of former vice president Dick Cheney, announced plans Tuesday to challenge Sen. Mike Enzi (R-Wyo.) in 2014, setting up an unexpected and probably costly primary contest as the Republican Party seeks to retake control of the U.S. Senate.

Enzi fielded questions from dozens of reporters Tuesday afternoon shortly after he voted against the nomination of Richard Cordray to lead the Consumer Financial Protection Bureau. His Cowboy State colleague, Sen. John Barrasso (R-Wyo.), stood by his side during the exchange and also fielded questions.

Below is a partial transcript of their remarks. The questions are paraphrased, while the responses are direct quotes.
