Top government lawyers representing 19 U.S. states on Wednesday asked a federal judge in California to force the administration of President Donald Trump to make health care subsidy payments that Trump abruptly cut off last week.

Anthem, one of the nation’s major health insurance companies, said on Wednesday that it planned to start its own business to manage prescription drug plans by partnering with CVS Health, the large pharmacy benefit manager and drugstore chain.

President Trump signed an executive order on Thursday morning that he said would begin “saving the American people from the nightmare of Obamacare.” On Thursday evening, he announced he would stop making scheduled payments to insurance companies that help them lower deductibles for low-income customers. There’s a lot that’s still uncertain about how the two actions will change the health law. Here’s what we know so far.

A pair of leading Republican and Democratic senators reached an agreement Tuesday to fund key federal health-care subsidies that President Trump ended last week — and the president expressed support for the plan.

Facing a Sunday deadline to approve or reject measures passed by the legislature this year, Brown weighed in on some key health care bills, including measures to protect Californians who buy insurance for themselves.

In an aggressive move to dismantle Obamacare, President Trump announced Thursday that the government was ending payments to health insurers that help fund the law.
