Sen. Kamala Harris, D-Calif., at podium, cheers health care workers to save the Affordable Care Act across the country outside LAC+USC Medical Center in Los Angeles, Sunday, Jan. 15, 2017. The rally was one of many being staged across the country in advance of President-elect Donald Trump’s inauguration on Jan. 20. Trump has promised to repeal and replace the health care law, and the Republican-controlled Senate on Thursday passed a measure taking the first steps to dismantle it.
