After President Donald Trump ordered a freeze on federal grants and loans, Medicaid's portals went down Tuesday afternoon, causing recipients to panic about their health insurance coverage. White House press secretary Karoline Leavitt confirmed the Medicaid outage Tuesday on X, formerly Twitter, but said payments would not be impacted.

Medicaid is a joint federal and state program that provides health care coverage to low-income individuals and families. It services over 79 million Americans.

So far, experts say it's uncertain how Medicaid funding could be disrupted by the funding freeze. Medicaid serves low-income Americans who often do not qualify for health insurance via their work. More than 74 million Americans were enrolled in Medicaid in the fall of 2024 and could be impacted by the funding freeze.
