Missouri Sen. Claire McCaskill announced minutes ago that she has breast cancer and will be spending three weeks away from Congress to receive treatment. McCaskill’s statement:

I very recently learned that I have breast cancer. It was detected through a regular mammogram. It’s a little scary, but my prognosis is good and I expect a full recovery. I will be in St Louis for the next 3 weeks receiving treatment. During this time my staff will continue to assist Missourians and I will be posting on my Senate website ( how I would have voted on any matters that come before the Senate during my absence—which I’ll also enter into the Congressional record. Additionally, I’ll be submitting questions in writing for any missed Senate hearings.

Thank you for the honor of serving you in the Senate.

(In case you were curious, McCaskill is not on the Judicary Committee.)

McCaskill, a Democrat, has served in the Senate since 2007. A popular figure who was re-elected by a 15-point margin in 2012 even as Mitt Romney won Missouri’s electoral votes, she’s become known on the national stage for her entertaining candor and her advocacy on behalf of sexual assault victims on college campuses and in the military.
