Connolly stepping down as top Democrat on Oversight Committee

• "The sun is setting on my time in public service," he wrote in an open letter to his constituents.

State of play: Connolly, 75, said last November that he was diagnosed with esophageal cancer.

• He defeated Rep. Alexandria Ocasio-Cortez (D-N.Y.) the following month to succeed Rep. Jamie Raskin (D-Md.) as the top Democrat on Oversight.
• Connolly's health made him a target of high-profile progressives outside of Congress who said he was unsuited for the role.

What he's saying: "When I announced my diagnosis six months ago, I promised transparency. After grueling treatments, we've learned that the cancer, while initially beaten back, has now returned," he wrote.

• "This will be my last term in Congress. I will be stepping back as Ranking Member of the Oversight Committee," he continued.
• "With no rancor and a full heart, I move into this final chapter full of pride in what we've accomplished together over 30 years."

What's next: Connolly has talked to Rep. Stephen Lynch (D-Va.), the third next senior Democrat on the panel after Del. Eleanor Holmes Norton (D-D.C.), about filling in for him, according to sources familiar with the matter.

• His departure paves the way for Ocasio-Cortez to run again, with Reps. Ro Khanna (D-Calif.), Robert Garcia (D-Calif.) and Jasmine Crockett (D-Texas) also being floated for the role.
• Behind that is an even deeper bench, with some House Democrats naming Reps. Maxwell Frost (D-Fla.) and Melanie Stansbury (D-N.M.) as possible candidates.
• House Democrats told Axios that Ocasio-Cortez is seen as a potential frontrunner if she opts in, but House Democratic caucus rules require her to obtain a waiver because she does not currently serve on Oversight.
