JOHNSTON, R.I. — Hundreds of residents filled the Johnston Senior Center on Sunday, rallying against the proposed dismantling of the Affordable Care Act, also known as Obamacare.

U.S. Senators Jack Reed and Sheldon Whitehouse and U.S. Reps. Jim Langevin and David Cicilline led the rally, joined by Rhode Island workers, seniors, families and health experts.

It is one of several rallies around the country held by Democrats ahead of President-elect Donald Trump's inauguration. Trump has promised a speedy repeal and replacement of the law that was one of Obama's proudest achievements.

The law delivered health coverage to about 20 million people but is saddled with problems such as rapidly rising premiums and large co-payments.

Republicans in Congress have begun the process of repeal.
