CHEYENNE, Wyo. (AP) — U.S. Sen. Mike Enzi says he will continue to do what he believes is right, even if it's not popular, as he faces a Republican primary challenge from Liz Cheney.

Enzi has kept a low profile since the daughter of the former vice president announced her campaign Tuesday. In a news release issued Thursday, he says he will continue focusing on the job he was elected to do.

He says people are calling and emailing to offer support. Enzi says he is confident Wyoming voters will support his "results, dedication, legislative experience and hard work."
