Texas leaders have shown a decadeslong antipathy toward Medicaid, the federal-state health insurance program that covers millions of low-income and vulnerable residents. They declined additional federal money that, under the Affordable Care Act, would have allowed Medicaid to offer health care coverage to more low-income families. The state was among the last to insure women for an entire year after they gave birth. And when the federal government last year ended a policy that required states to keep people on their Medicaid rolls during the coronavirus pandemic, Texas officials rushed to kick off those they deemed ineligible, ignoring persistent warnings that the speedy process could lead to some people being wrongfully removed.
