John Bolton says he helped plan foreign coups

What he's saying: "Ultimately, he did unleash the rioters at the Capitol. As to that, there’s no doubt," the former U.S. ambassador to the United Nations asserted.

• "As somebody who has helped plan coup d’état, not here but other places, it takes a lot of work, and that's not what he did," he added.

The intrigue: Although Bolton said he wouldn't go "into specifics" on which countries he'd assisted coups in, he noted that he'd written in his book about efforts in Venezuela to end Nicolás Maduro's regime that "turned out not to be successful — not that we had all that much to do with it."

• "But I saw what it took for an opposition to try and overturn an illegally elected president, and they failed," Bolton said. "The notion that Donald Trump was half as competent as the Venezuelan opposition is laughable."
