Bill Ayers, the Weather Underground co-founder who once supported President Obama, now thinks the commander-in-chief should be put on trial for war crimes.

Ayers made the comments during an interview with Real Clear Politics. The former leader of a domestic terror group ripped the sitting president over his continuation of the U.S. drone program.

Asked if Obama should go on trial for war crimes, he said: "Absolutely, every president in this century should be put on trial" at The Hague.

"Every one of them goes into office, an office dropping with blood and then adds to it," he said. "And yes, I think that these are war crimes. I think they're acts of terror."

Obama, during a speech last month on counterterrorism policy, defended his administration's practice of taking out terror operatives overseas with drone strikes. He also announced new checks on the program.

Obama has tried to distance himself from Ayers, who previously lived in the same neighborhood as Obama and once served on a charitable board with him.

The Weather Underground, when it was active during the Vietnam War period, carried out a series of bombings against U.S. government buildings.
