(AP) - Federal officials investigating the San Bernardino terror attack are trying to determine whether the U.S. government missed any warning signs reflecting the couple's apparent radicalization in recent years.
FBI Director James Comey has said Syed Rizwan Farook and his wife, Tashfeen Malik, voiced extremist views online as early as 2013.
Comey and other officials briefed Congress on Thursday.
Republican Rep. Will Hurd of Texas, a member of the House Homeland Security Committee, said there's currently no evidence Malik's radicalization would have been readily apparent when she was evaluated for a fiancée visa.
Even so, the fact she received a visa despite having earlier discussed jihad and martyrdom has led to scrutiny of the visa system.
