Sen. Dianne Feinstein (Calif.), the ranking Democrat on the Senate Intelligence Committee, on Thursday will introduce legislation broadening the debate to visa waivers granted to European citizens traveling to the United States.

The legislation, co-sponsored by Sen. Jeff Flake (R-Ariz.), would block waivers for European citizens who spent time in Syria or Iraq in the past five years.
“Let’s say France has had 2000 people leave to go and fight [in Syria.] They’re a visa waiver country so the people come back to France and then they come into the United States. The bill we would propose would strictly limit that,” she said after attending a classified briefing with senior administration officials Wednesday evening. 

She added the legislation would tighten the fingerprinting requirements for visitors who qualify for visa waivers.
