CNN reports Tashfeen Malik pledged allegiance to the leader of ISIS on the same day she and her husband killed 14 people in San Bernardino, California, according to law enforcement. According to Jim Sciutto, CNN's chief national security correspondent, Malik allegedly posted a note of support for ISIS leader Abu Bakr al-Baghdadi, under a different account name, either during or before the deadly attacks. The report comes via several federal officials who've investigated the electronic devices the attackers used.
