WASHINGTON --Setting a hard-line tone on national security, President Donald Trump on Friday suspended the nation's refugee program for four months, aiming to keep "radical Islamic terrorists" out of the United States.
Trump traveled to the Pentagon, where he joined Defense Secretary Jim Mattis for the signing of an executive action to bring sweeping changes to the nation's refugee policies and put in motion his plans to build up the nation's military.
"We want to ensure that we are not admitting into our country the very threats our soldiers are fighting overseas," he said. "We only want to admit those into our country who will support our country and love deeply our people."
The order was signed on Trump's most robust day of national security and foreign policy at the start of his presidency, marked by a meeting with British Prime Minister Theresa May and a lengthy phone call with Mexican President Enrique Pena Nieto.
During his election campaign against Hillary Clinton, Trump pledged to put in place "extreme vetting" procedures to screen people coming to the U.S. from countries with terrorism ties. The order imposes a 120-day suspension of the entire U.S. Refugee Admissions Program and a 90-day ban on all entry to the United States from countries with terrorism concerns.
The State Department said the three-month ban in the directive applied to Iraq, Syria, Iran, Sudan, Libya, Somalia and Yemen - all Muslim majority nations.
The order also halts entry to the U.S. by Syrian refugees until the president determines that changes to the refugee assistance program ensure that admitting them won't compromise national security.
The order makes no mention of a plan to provide safe zones in Syria and the surrounding area. A draft of the order had directed the Pentagon and the State Department to produce a plan for safe zones in the war-torn Mideast nation.
The Council on American-Islamic Relations, or CAIR, said it would file a federal lawsuit Monday challenging the constitutionality of the executive order.
"There is no evidence that refugees - the most thoroughly vetted of all people entering our nation - are a threat to national security," said CAIR National Litigation Director Lena F. Masri. "This is an order that is based on bigotry, not reality."
Trump also signed a presidential memorandum on "rebuilding" the U.S. Armed Forces, giving Mattis 30 days to conduct a "readiness" review and report back on steps that can be taken this year to improve conditions.
Joined earlier in the day at the White House by May, the British prime minister, Trump reaffirmed the United States' "special relationship" with Great Britain.
But he was also asked about more contentious issues, including his recent statements that torture "does work" in prying information out of terror suspects. Giving ground, he said his defense secretary's opposition would override his own belief. Hours later he stood at the Pentagon as Mattis, the retired general, was sworn in as the military's chief.
Trump was also pressed on whether he would revert back to Bush-era use of torture, in the news since The Associated Press and other news organizations obtained copies of a draft executive order signaling sweeping changes to U.S. interrogation and detention policy.
Trump said he would defer to the views of Mattis, who has questioned the effectiveness of such practices as waterboarding, which simulates drowning.
"He has stated publicly that he does not necessarily believe in torture or waterboarding, or however you want to define it. ... I don't necessarily agree. But I would tell you that he will override because I'm giving him that power. He's an expert," Trump said.
The draft order, which the White House said was not official, also would reverse Obama's effort to close the military detention center at Guantanamo Bay, Cuba - a place Trump has said he wants to fill up "with bad dudes."
The draft also requests recommendations on whether the U.S. should reopen CIA detention facilities outside the United States. Critics said the clandestine sites have marred America's image on the world stage.
Trump held firm Friday on another controversy - trade and illegal immigration from Mexico. He told reporters at a joint news conference with May that he had a "very good call" with Pena Nieto earlier in the day, but he reaffirmed his belief that Mexico has "outnegotiated and beat us to a pulp" on trade - and that would change.
"We're no longer going to be the country that doesn't know what it's doing," he declared a day after the Mexican leader canceled his visit to Washington in response to Trump's plans to build a border wall and have Mexico pay for it.
While the refugee actions are aimed at thwarting terrorists, the border wall is more for keeping out immigrants trying to enter the U.S. for economic reasons - though Trump has continually also raised concerns about criminals flowing north.
The flurry of national security moves and foreign policy outreach capped a hectic first week for Trump at the White House, giving Americans an initial look at how he intends to position the United States around the globe.
Trump, who met with the Joint Chiefs of Staff at the Pentagon, has the authority to determine how many refugees are accepted annually, and he can suspend the program at any time. Refugee processing was suspended in the immediate aftermath of the Sept. 11 attacks and restarted months later.
During the past budget year, the U.S. accepted 84,995 refugees, including 12,587 people from Syria. President Barack Obama had set the refugee limit for this budget year at 110,000.
Trump, according to the executive order, plans to cut that to 50,000. The order says that while the program is suspended, the U.S. may admit people on a case-by-case basis when "in the national interest" and the government will continue to process refugee requests from people claiming religious persecution, "provided that the religion of the individual is a minority religion in the individual's country." That suggests it would allow the admission of Christians from Muslim-majority countries.
In an interview with CBN News, Trump said persecuted Christians would be given priority in applying for refugee status. "We are going to help them," Trump said. "They've been horribly treated."
Applauded by some in his own party, Trump's refugee action was strongly criticized by some Democrats.
"Tears are running down the cheeks of the Statue of Liberty tonight as a grand tradition of America, welcoming immigrants, that has existed since America was founded has been stomped upon," said Senate Minority Leader Chuck Schumer of New York.
Trump's order was signed on Holocaust Remembrance Day, which brought to mind the global effort to help refugees during World War II and its aftermath.
On another international issue, Trump is expected on Saturday to speak by phone with Russian President Vladimir Putin. During the news conference with May, he was asked if he was considering lifting U.S. sanctions against Russia. But Trump was noncommittal, saying, "We'll see what happens. As far as the sanctions, very early to be talking about that."
Obama's administration and the European Union slapped Moscow with sanctions for its annexation of Ukraine's Crimean Peninsula and support for a pro-Russia insurgency in eastern Ukraine. Relations have plunged to post-Cold War lows over Ukraine, Putin's backing of Syrian President Bashar Assad and allegations of Russian meddling in the U.S. elections.
May, for her part, said the United Kingdom supports continuing the sanctions for now.
