Texas Sen. Kay Bailey Hutchison, a Republican, will not seek reelection in 2012, the Dallas Morning News reports.
"I am announcing today that I will not be a candidate for re-election in 2012," wrote the three-term senator to supporters on Thursday. "That should give the people of Texas ample time to consider who my successor will be."
The Fort-Worth Star Telegram reported last month that the GOP lawmaker would have a Tea Party target on her back if she decided to run.
"She personifies everything that the Tea Party is fighting," said one member of a local Texas Tea Party steering committee. "She is a Republican, but when you check her votes on many issues, they are not ones that conservatives are happy with."
As for who might run to secure Hutchison's seat, according to the Telegram:
Republicans such as former Secretary of State Roger Williams and Railroad Commissioners Michael Williams and Elizabeth Ames Jones, along with Democratic former Comptroller John Sharp -- have long said they plan to run.
