The White House gave no details as to what it may do, but the administration official suggested that the contours of the United States’ refugee program, which as of now accepts up to 70,000 people a year, were being examined. If the administration decides to let in more refugees, it could prompt a backlash among Republicans who fear terrorists lurk among those seeking aid.

“The administration is actively considering a range of approaches to be more responsive to the global refugee crisis, including with regard to refugee resettlement,” said Peter Boogaard, a spokesman for the White House’s National Security Council. “We are also in regular contact with countries in the Middle East and Europe who have been greatly impacted by the increased refugee flows.”
