Aaron Klein begins a Sept. 13 WorldNetDaily article by asking, "Is the U.S. supporting the very Islamic groups now attacking the country’s diplomatic missions in Libya and Egypt?" The answer is no, but Klein never actually comes out and says that.
Klein notes that "some of the gunmen attacking the U.S. installation had identified themselves as members of Ansar al-Shariah, which represents al-Qaida in Yemen and Libya, but then slips into his dishonest guilt-by-association mode, claiming that "the U.S.-aided rebels that toppled Muammar Gadhafi’s regime in Libya consisted of al-Qaida and jihad groups" and that "the Obama administration is currently aiding the rebels fighting Bashar al-Assad’s regime in Syria amid widespread reports that al-Qaida jihadists are included in the ranks of the Free Syrian Army." Klein even rehashes a previous allegation that a "senior Syrian source" -- Klein loves his unverifiable, anonymous sources -- says "hardcore mujahedeen" are taking part in the Syrian resistance.
At no point does Klein prove that the U.S. is "supporting" Ansar al-Shariah or even that Ansar al-Shariah was a part of the rebel opposition in Libya.
In other words, it's just more dishonest reporting from Klein, who's more interested in trying to destroy President Obama than telling the truth.
