Rep. Stephanie Murphy of Florida, a leader among the moderate wing of House Democrats, announced Monday that she will retire after her current term and not seek reelection in 2022.

“I’ve decided not to seek another term in Congress. Serving Central Florida has been the honor of my life, but it’s also been incredibly challenging for my family and me,” the Florida Democrat wrote on Twitter.

“This was not an easy decision, but it is the right decision,” Murphy said.
