MCCASKILL: Two years ago, I beat breast cancer. Like thousands of other women in Missouri, I don't talk about it much, but those who face cancer and many other illnesses have a pre-existing condition when it comes to health coverage. Unfortunately, Josh Holley filed a lawsuit, letting insurance companies deny coverage for those with pre-existing conditions. That's just wrong, and I'm fighting to stop it. I'm Claire McCaskill and I approve this message because the insurance companies already have too many senators on their side.
