Stop the sneak attack on Medicare.

There is a trade agreement being negotiated behind closed doors that will have broad-reaching impacts on the American economy. Called Trans-Pacific Partnership—or TPP—this trade deal is set to be fast-tracked through Congress, before the American public has the chance to weigh in.Not only is there a risk to American jobs, but as currently written, the deal could raise Medicare prescription drug costs.

But on Tuesday, something happened that no one expected: Thanks to the leadership of Senators Harry Reid, Elizabeth Warren, Sherrod Brown and Bernie Sanders, the slowed down the progress of Fast Track trade authority for the Trans-Pacific Partnership (TPP) by blocking a key test vote.

While this is a real victory for people-powered movements, a rotten compromise package has reared its head that would pay for worker re-training with $700 million in cuts to Medicare funding.

Out of pocket health care costs already consume more than a third of the average Social Security check. If that amount increases, that’s just as bad as the cuts to our Social Security system that we’ve been fighting. The fact that health care costs have increased faster than Social Security’s cost of living adjustments just proves that Social Security needs to be expanded—not cut. And cuts to people with Medicare are effectively cuts to Social Security.

Tell the Senate: Stop the sneak attack on Medicare!
