CHEYENNE, Wyo. (AP) — Former Vice President Dick Cheney's daughter Liz Cheney says she will run against Wyoming's senior U.S. senator in next year's Republican primary.

She announced her campaign in a statement Tuesday, and the news was confirmed by her campaign manager, Kara Hearn.

Also on Tuesday, U.S. Senator Mike Enzi announced his intent to seek re-election next year for a fourth term in office.

Liz Cheney is 46 and the elder of Dick Cheney's two daughters.

She has been in the public eye in recent years as a Fox News political commentator. Last year, Cheney and her husband bought a home in Jackson Hole.

Since then, Cheney has been a frequent speaker at Republican Party events in the state.

She holds a law degree from the University of Chicago and has worked for the State Department and the Agency for International Development.

Enzi, a former state legislator and mayor of Gillette, was first elected to the Senate in 1996.

Enzi emphasized on Tuesday that he intends to concentrate on serving in the Senate until the campaign gets under way.
