John McConnell, a federal judge, said that the Trump administration was defying an order he issued on January 29th directing it to unfreeze federal grants and other payments. It is the first time a judge has accused the administration of ignoring court orders.

The moves reflect the new administration’s dizzying pace as the president and his allies seek to remake the federal government.

Trump administration officials have criticized federal court rulings over policies that could lead to showdown over executive power.

Yesterday, the president said that no judge “should be allowed” to rule against the changes his administration is making.
