Democratic Congressman Bart Stupak of Michigan said he'll retire from Congress rather than seek a 10th term this year.
Stupak made the comments to The Associated Press, but the information was also confirmed by NBC News.
Stupak has drawn stinging criticism from opponents of the recently enacted health care overhaul after leading a bloc of anti-abortion Democrats whose last-minute support was crucial to its approval by the House.
The Tea Party Express is calling for his defeat at rallies in his sprawling northern Michigan district this week.
But Stupak tells the AP the attacks didn't influence his decision and he could win re-election if he tried.
He plans to announce his decision at a 12:30 p.m. news conference at Northern Michigan University in Marquette.
He says he wants to spend more time with his family and start a new career after 18 years in Congress.
