SDS was a radical communist/socialist group in the 1960's. Most of President Obama's Czars were members of this group, such as Jim Wallis, Obama's spiritual advisor. For a time, members of SDS were wanted by the FBI, including Mike Klonsky, Bernadine Dohrn, and Bill Ayers. Bill Ayers is a close friend and advisor to President Obama. Bernadine Dohrn is married to Bill Ayers. Mike Klonsky and Bernadine Dohrn worked closely together while a part of SDS. Terrorist groups also came out of SDS like the Weather Underground, which Bill Ayers was a part of. They blew up the Pentagon, and when asked if he regretted it, Bill Ayers said he wished he had done more.
