Mueller will soon indict 'a significant number of names quite familiar to the average American': Ex-CIA director

Former CIA director John Brennan predicted more indictments would be coming soon in special counsel Robert Mueller's probe -- and he suggested those could include members of President Donald Trump's family.

Brennan, now an MSNBC analyst, appeared on "Morning Joe" just moments after FBI agents arrested Trump campaign associate Roger Stone on seven counts as part of Mueller's investigation of Russian election interference.

"In the summer of 2016 we were watching what was happening in terms of what was being released by WikiLeaks and how the Russian hand was behind this," Brennan said. "So the intermediary was something looked at very closely by the FBI and others, so again, this indictment is not surprising in any respect."

"I expect in the next 60 days you're going to have a fair number -- a significant number of indictments. I think people are waiting for the report that is coming out from Robert Mueller. What I look for most are the indictments. It's so rich in detail, to me all of these indictments will be basically the compendium of Robert Mueller's, the special counsel's investigation."

"I expect there to be a significant number, and a significant number of names that will be quite familiar to the average American," he added.

Brennan said he and then-FBI director James Comey were investigating in summer 2016 the links between the Trump campaign and Russian efforts to influence the election.

"There was an extensive effort to try to influence the outcome of the election that involved the Russians, that involved U.S. persons and that may have gone to the very top of the Trump campaign," he said. "I think the shoes that are yet to drop are going to be the ones that are going to be the most profound and that will hit the people at the top of the organization."

That could potentially include the president himself.

"It may be, it may not," Brennan said.
