Yep.
Recently noted, Bill Ayers getting together with Carl Dix.
Dix is a longtime mouthpiece for the RCP.
Also, the RCP was active at Occidental College when Obama was there and was, by his own admission, interacting with Marxists.
Obama’s green czar, Van Jones, who was forced to resign during Al’s first term, also walked and talked like an RCPer.
"in jail, he [Van Jones] said, "I met all these young radical people of color -- I mean really radical, communists and anarchists [Rodney King protests]. And it was, like, 'This is what I need to be a part of.'" Although he already had a plane ticket, he decided to stay in San Francisco. "I spent the next ten years of my life working with a lot of those people I met in jail, trying to be a revolutionary." In the months that followed, he let go of any lingering thoughts that he might fit in with the status quo. "I was a rowdy nationalist on April 28th, and then the verdicts came down on April 29th," he said. "By August, I was a communist."

"The RCP [Revolutionary Communist Party] upheld the 1992 sometimes-violent unrest in Los Angeles and nationally as a 'rebellion' in the aftermath of the Rodney King verdicts. Then-LAPD chief Daryl Gates alleged that the RCP was involved in the 'riots'. Los Angeles has long been one of the RCP's larger and more active branches. William 'Mobile' Shaw was a local leader who recently passed and received public commendation from the party."
