WASHINGTON (AP) — The government allowed “a small but significant number” of terrorists into America’s witness protection program and then failed to provide the names of some of them for a watch list that’s used to keep dangerous people off airline flights, the Justice Department’s inspector general says.

As a result of the department’s failure to share information with the Terrorist Screening Center, some in the witness protection program who were on a government “no-fly” list were allowed to travel on commercial flights, the department’s watchdog said.
