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

WASHINGTON (Reuters) -At least three U.S. lawmakers said on Tuesday healthcare providers were blocked from the Medicaid payment portal after the Trump administration announced a federal funding pause, even as the White House said the program was exempted.

The White House budget office on Wednesday rescinded an order freezing federal grants, according to a copy of a new memo obtained by The Washington Post, after the administration’s move to halt spending earlier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