(T.J. Kirkpatrick | The New York Times) Seema Verma, the Centers for Medicare and Medicaid Services administrator, speaks at the White House as President Donald Trump looks on in Washington on Nov. 15, 2019. The Trump administration said Thursday, Jan. 30, 2020, that it would start allowing states to seek fixed amounts of money for most poor working-age adults who receive Medicaid coverage, a major shift that would limit federal contributions to a portion of a program that has always been an open-ended entitlement.
