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

President Donald Trump‘s administration sought to tamp down confusion over Medicaid funding in the wake of Office of Management and Budget director Matthew Vaeth’s memorandum pausing federal grant funding.

White House press secretary Karoline Leavitt said that Social Security, Medicare and food stamps would not be affected by the decision to freeze federal aid. NBC News’ Sahil Kapur reports on the Trump administration’s first White House press briefing and whether Medicaid could be among the programs affected.
