Hillary Clinton backed efforts to alter Obamacare on Wednesday, but also used her remarks to a health care group in Florida to offer a full defense of the sweeping and controversial law.

“I think we are on the right track in many respects but I would be the first to say if things aren’t working then we need people of good faith to come together and make evidence-based changes,” the former secretary of state and possible 2016 presidential candidate said.

In particular, Clinton pointed to issues with “small business of 50 or more” providing coverage to their employees, and businesses “moving people from full-time work to part-time work to try to avoid contributing to their health care” as issues that should be addressed.
