At least two of a panel of three federal judges who in an appellate court on Thursday ruled against President Donald Trump in the controversial travel ban order, have had to increase their security detail amid a number of threats, law enforcement officials said.

According to a report on CNN, local and federal law enforcement agencies were treating the threats seriously, increasing patrols and personal security for the judges.

A spokesperson for the US Marshals Service said that while the agency does not “discuss our specific security measures, we continuously review the security measures in place for all federal judges and take appropriate steps to provide additional protection when it is warranted.”

Earlier, in a unanimous decision, the San Francisco-based 9th US Circuit Court of Appeals declined Thursday to block a lower-court ruling that suspended the executive order preventing travelers from seven Muslim-majority nations from entering the US.

“We hold that the government has not shown a likelihood of success on the merits of its appeal, nor has it shown that failure to enter a stay would cause irreparable injury,” the judges ruled.

Trump said the ruling was a “political decision,” and promised to “see [them] in court.”

Trump, in a brief, impromptu appearance in the West Wing, said the “security of our country is at stake” but did not specify what his administration’s next legal steps would be. His comments were recorded by the network pool at the White House.

Trump said he did not believe the decision undercut his presidency and vowed his administration will “win the case.”

The Justice Department said it was “reviewing the decision and considering its options.”

The White House could appeal the judge’s restraining order to the US Supreme Court or it could attempt to make the case for the travel ban in the district court.

White House counselor Kellyanne Conway suggested the next step would be to argue the merits of the executive order.

“The statute provides a president … with great latitude and authority to protect the citizens and to protect the nation’s national security,” Conway said. “This was not argued on the merits. Now that we’ll have an opportunity to argue on the merits we look forward to doing that. We look forward to prevailing.”

The ruling represented a setback for Trump’s administration and the second legal defeat for the new president in the past week. Trump’s decision to sign the executive order late last month has sparked protests at airports around the world as authorities barred scores of travelers from entering the country amid confusion over how to implement the details.

The appellate decision brushed aside arguments by the Justice Department that the president has the constitutional power to restrict entry to the United States and that the courts cannot second-guess his determination that such a step was needed to prevent terrorism.

Shortly after the ruling, Trump tweeted, “SEE YOU IN COURT, THE SECURITY OF OUR NATION IS AT STAKE!”

Senate Minority Leader Chuck Schumer tweeted Thursday that Trump “ought to see the writing on the wall” and abandon the proposal. The New York Democrat called on the president to “roll up his sleeves” and come up with “a real, bipartisan plan to keep us safe.”

House Democratic leader Nancy Pelosi of California promised, “Democrats will continue to press for President Trump’s dangerous and unconstitutional ban to be withdrawn.”

Trump’s election rival Hillary Clinton tweeted simply: “3-0.”

US District Judge James Robart in Seattle issued the temporary restraining order halting the ban last week after Washington state and Minnesota sued, leading to the federal government’s appeal.

The Trump administration has said the seven nations — Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen — have raised terrorism concerns. The states have argued that the executive order unconstitutionally blocked entry based on religion and the travel ban harmed individuals, businesses and universities.

The president, in his third week in office, has criticized the judiciary’s handling of the case. Last weekend, he labeled Robart a “so-called judge” and referred to the ruling as “ridiculous.” Earlier this week he accused the appellate court considering his executive order of being “so political.”

Trump’s Supreme Court nominee, Judge Neil Gorsuch, has referred to the president’s comments as “demoralizing and disheartening,” according to a Democratic senator who asked him about Trump’s response.
