U.S. Rep. Chellie Pingree's campaign says the Democrat is considering a run for Maine governor.
Pingree's spokesman, Jesse Connolly said the congresswoman will decide whether to join the 2018 race by the end of December. Nearly two dozen hopefuls have registered to run for governor, and Pingree would join 10 Democratic candidates.
Republican Gov. Paul LePage cannot seek re-election because of Maine's term limits law.
Pingree, a progressive Democrat, has represented Maine's 1st Congressional District since 2009. The former organic farmer served in the Maine Senate from 1992 to 2000 and served as Senate majority leader.
She has often criticized Republican President Donald Trump and his policy positions.
Pingree won re-election to Congress with 58 percent of the vote in 2016. She sits on the appropriations committee in the House.
