CHEYENNE, Wyo. (AP) — U.S. Rep. Cynthia Lummis will announce her re-election bid to represent Wyoming's lone seat the U.S. House.

The Republican's campaign organization says she has scheduled an announcement for Monday afternoon in Cheyenne.

Lummis was first elected to the House in 2008, replacing Barbara Cubin, who retired after seven terms.

She easily won re-election in 2010, defeating Democrat David Wendt with more than 70 percent of the vote.

So far, two candidates have announced plans to challenge Lummis this year.

Casper College political science instructor Chris Henrichsen is running as a Democrat, and former Roman Catholic priest Charlie Hardy announced he will run as an independent.
