US President Donald Trump has attacked the judge who blocked his travel ban, saying Americans should blame the courts “if something happens”.
Mr Trump also said he had instructed border officials to check people entering America “very carefully”.
The Federal Appeals Court on Saturday rejected the Trump administration’s request to reinstate the ban.
The ban, affecting people from seven mainly-Muslim countries, was blocked by Seattle’s federal judge on Friday.
In its appeal, the Justice Department said Judge Robart had overreached by “second guessing” the president on a national security matter.
It also argued that only the president could decide who can enter or stay in the US.
The two states challenging the restriction – Washington and Minnesota – argued that the ban was unconstitutional and denied people with valid entry documents the right to travel without due process.
