There is no evidence - other than a screen shot that shows Huma as an assistant editor of a group founded by her now deceased father - that Huma herself either is or embraces Muslim Brotherhood. Both of her parents - and her brother - are quite a different story.
The Institute on Muslim Minority Affairs (IMMA) - the group founded by her now-deceased father - had the quiet support of Al-Qaeda Godfather Abdullah Omar Naseef, who was also General Secretary of the MWL, a group that supported Al-Qaeda. Huma's mother, Saleha Abedin, is a confirmed member of the Muslim Sisterhood. Those facts make this statement by McCain on the Senate floor demonstrably false:
“Huma Abedin represents what is best about America,” said McCain. “The daughter of immigrants who has risen to the highest levels of our government on the basis of her substantial personal merit and her abiding commitment to the American ideals that she embodies.”“I am proud to know her,” McCain continued. “And I am proud – even with some personal presumption – to call her my friend.”
Abedin's parents were not immigrants; they were infiltrators with confirmed - and very close - connections to an Al-Qaeda leader.
Saleha Abedin, along with her late husband Syed Z. Abedin, were also founders of the Institute of Muslim Minority Affairs, a London organization that is known to have been close at one time to the Saudi Muslim World League.John McCain is coming precariously close to a legacy similar to that of Henri-Philippe Petain, a French WWI hero who became a traitor in WWII when he conspired with the Nazis.
Yes, it's that serious. By ignoring the Brotherhood / Al-Qaeda connections of Huma's family, McCain is taking far too much on faith.
The connections of Huma's parents should have prevented her from passing a background check for the position she now holds. That's just a fact and McCain is egregiously wrong.
