AUSTIN, Texas (AP) - U.S. Sen. Kay Bailey Hutchison said in a radio interview that she expects to step down from the Senate around October or November to battle fellow Republican Rick Perry for governor.

In an interview Wednesday on WBAP-AM of Fort Worth and Dallas, Hutchison said she wants to stay in the Senate long enough to fight President Barack Obama's healthcare plan. She said her departure will be some time in "October, November, in that time frame."

She again said that she'll officially launch her gubernatorial campaign in August.

The Republican senior senator from Texas said that, in effect, she gave Perry a free pass four years ago when she decided not to run against him. She said he's now trying to stay in the job too long.
