U.S. President Donald Trump moved to undermine Obamacare dramatically late on Thursday by cutting off subsidies to health insurance companies for low-income patients, sparking threats of legal action and concern of chaos in insurance markets.
The decision is the most dramatic action Trump has taken yet to weaken the Affordable Care Act, President Barack Obama's signature health care law, which extended insurance to 20 million Americans.
The move drew swift condemnation from Democrats and threats from state attorneys general in New York and California to file lawsuits.
