Lawmakers are encouraging other elected officials to participate in protests

(CNN) Sens. Chuck Schumer and Sen. Bernie Sanders called on constituents and their fellow senators from across the country to lead rallies protesting President Donald Trump's plan to repeal the Affordable Care Act later this month.

"The Republican Party's plan to repeal the Affordable Care Act is in chaos," the two lawmakers said in a joint statement Saturday. "The American people increasingly understand that throwing 20 million people off health insurance, privatizing Medicare, raising prescription drug costs for seniors and doing away with life-and-death patient protection provisions is not acceptable."

Schumer recently spoke at a rally advocating for exanding LGBT rights, and Sanders is reaching out to other senators encouraging them to protest.

"We are encouraging Democratic senators to lead rallies in their states. This is not a Democratic issue, a Republican issue or an Independent issue," they wrote. "The overwhelming majority of Americans, regardless of political persuasion, understand that we have to go forward on health care, not backwards."

A CNN/ORC poll from last month found more people viewed the law favorably as opposed to unfavorably, 49%-47%. In that poll, a majority would prefer the GOP to repeal parts of the law only if replacements can be enacted at the same time (55%). Fewer overall say they ought to repeal parts of the law as they can, regardless of their ability to replace those pieces (21%) and another 1-in-5 (22%) say they'd prefer the Republicans to abandon their plans to repeal the law entirely.
