At least 23 people attempting to illegally cross the southern border in 2021 were on the terror watch list maintained by the FBI, according to a report.

Fox News on Monday revealed that U.S. Customs and Border Protection data shows that between Jan. 20 and Dec. 27, 2021, there were 23 border encounters with individuals whose names were on the FBI’s Terrorist Screening Database.

Eleven encounters happened in Texas, four in Arizona, and eight in California, according to data Fox News reportedly obtained through a Freedom of Information Act request filed in December.
