They got Al Capone for tax evasion, and they may get Huma Abedin for "violating rules regarding vacation and sick leave" and for the "possible exchange of unsecured, classified data." To be sure, these are serious charges, and the available evidence makes it abundantly clear that there is ample warrant to investigate and perhaps even charge Abedin. However, it is a sign of a serious problem with today's political culture that even more serious allegations regarding Abedin have never been investigated, and almost certainly never will be.
Huma Abedin's Muslim Brotherhood connections have been fully exposed by Andrew McCarthy and bruited about for years. The facts are quite public, albeit largely ignored: Abedin's parents are both members of the Muslim Brotherhood, but her links to the organization are not just familial. Abedin was for twelve years the assistant editor of the Journal of Muslim Minority Affairs (JMMA), which was founded by Abdullah Omar Naseef, a Muslim Brotherhood operative and al-Qaeda financier. Naseef and Abedin both appeared on the JMMA's masthead from 1996 to 2003.
