CASPER, Wyo. (AP) — U.S. Rep. Cynthia Lummis says she has not ruled out running for Wyoming governor in 2018.

The 61-year-old Republican is not seeking re-election to Congress this year.

In 2018, the governor's race will be open. Gov. Matt Mead is serving his second four-year term and is prohibited by state law from seeking a third term.

Lummis says it's the right time for her to leave Congress but what the future holds for her politically she can't say for certain yet.

Lummis was the youngest woman elected to the Wyoming Legislature in 1979. She also served eight years as state treasurer before being elected to the U.S. House in 2008.
