White House Chief of Staff Denis McDonough failed to answer repeated questions on Sunday about why the U.S. after one year has failed to arrest Ahmed Abu Khattala, who has been charged in connection with the Benghazi attacks. “Why is it that reporters seems to be able to find this guy, who the government is charging with involvement in Benghazi, but law enforcement can’t find him?” Fox News host Chris Wallace asked, adding “it’s been a year, sir.”
