More than 5,000 people took to the streets of Philadelphia Thursday to protest Trump’s visit to the city and to denounce Republican policies, including the efforts to repeal the Affordable Care Act. Trump’s first executive order, signed only hours after his inauguration, made the “prompt repeal” of Obamacare the administration’s top priority. The administration has pulled ads for the 2017 enrollment season of Obamacare off the air—including the ads that were already paid for. The deadline to sign up for new plans is January 31.
