LANSING, Mich. (AP) — The White House has held a 90-minute conference call with governors about plans to increase the number of refugees accepted in the United States after governors raised concerns related to last week’s attacks in Paris.

The governors of Michigan, Pennsylvania, Vermont and other states participated Tuesday and asked questions of senior Obama administration officials.

A spokeswoman for Michigan Republican Gov. Rick Snyder says he appreciated the discussion and told officials he’d like “more robust data” on the refugee system.

Vermont Democratic Gov. Peter Shumlin says he has faith in the “rigorous” screening process outlined by administration officials and he reiterated to governors that terrorists win “when we give into fear.”

More than half of governors object to plans to resettle Syrian refugees here. But the federal government controls resettlement programs.
