Update: Washington Examiner said 15 states  have halted the program as of 3:40 PM EST.
Both Michigan and Alabama have halted the refugee program until further notice, reported Fox News :
The governors of Alabama and Michigan said Sunday that they would not resettle any refugees from Syria in their states, amid reports that at least one of the Paris attackers slipped through Europe’s immigration system and concerns about “gaping holes” impacting America’s screening process.
In Michigan, which has a large Arab-American population, Gov. Rick Snyder said he was putting his prior calls for the state to accept more refugees on hold until the Department of Homeland Security reviewed its screening procedures.
“Michigan is a welcoming state and we are proud of our rich history of immigration,” Snyder said in a statement. “But our first priority is protecting the safety of our residents.”
The governor later added, “It’s also important to remember that these attacks are the efforts of extremists and do not reflect the peaceful ways of people of Middle Eastern descent here and around the world.”
