Former Rep. Cynthia Lummis filed with the Federal Election Commission to run for Senate in Wyoming, setting up a potential clash with Rep. Liz Cheney — if her successor in Congress decides to run.
Lummis filed for the seat currently held by Sen. Mike Enzi, who announced last month that he was not seeking reelection.
Some Republicans have called for Cheney, a member of GOP leadership, to run for Enzi's seat, though she has not indicated whether she is considering it.Lummis, a former member of the conservative House Freedom Caucus, served four terms as the state's only representative in the House. She retired rather than run for a fifth term in 2016, and Cheney won the race to replace her.
Lummis' former chief of staff, Tucker Fagan, told the Casper Star-Tribune last month she was considering a run.
"She’s mulling her business, family, lifestyle and the possibility of a run," Fagan said.
