The White House Office of Management and Budget says its program freeze is limited, but states report widespread disruption in online Medicaid portals.

A funding freeze ordered by the Trump administration has sparked widespread confusion about its effects on government programs such as Medicaid.

The White House budget office on Wednesday rescinded an order freezing federal grants, according to a copy of a new memo obtained by The Washington Post, after the administration’s move to halt spending earlier this week provoked a backlash.
