A federal judge in Seattle blocked President Donald Trump's effort to halt the nation's refugee admissions system, ruling that it ran afoul of the system Congress created for moving refugees into the U.S. The judge stated that the president's actions amounted to an 'effective nullification of congressional will' in setting up the program. The ruling came in a lawsuit brought by major refugee aid groups, who argued that Trump's executive order suspending the federal refugee resettlement program was detrimental to the interests of the United States.
