White House documents show that the administration’s talking points on the September 2012 Benghazi attack were revised 12 times and scrubbed of references to CIA warnings and the al Qaeda-linked Ansar al Sharia group that perpetrated the attack.

Boston bombing suspect Tamerlan Tsarnaev was already a jihadist when he traveled to Russia in 2012, according to his cousin Magomed Kartashov, a leading Dagestani Salafist. Al Qaeda sympathizer Ahmed Abassi, who faces charges in a plot to bomb a passenger train, also had proposed poisoning US air and water.
