Former FBI official Frank Figliuzzi said he thinks special counsel Robert Mueller is "ready to indict some folks" with findings from his investigation into Russian interference in the 2016 presidential election.

Speaking to Brian Williams on MSNBC's "11th Hour" Thursday night, Figliuzzi, who worked with Mueller at the FBI, laid out Mueller's possible plan.

"I'm not saying he's indicting the president. I'm saying there's a middle ground where he tells us the story, locks it into the court system by indicting others, then files a report with [acting Attorney General Matthew] Whitaker," he said.

The former assistant director for counterintelligence at the FBI said Mueller could use indictments to depict President Trump's possible wrongdoing.

"Perhaps what we'll see is Bob Mueller telling us the story of a corrupt president through indictments," Figliuzzi said.

Figliuzzi predicted that Mueller's days could be numbered since Trump fired Attorney General Jeff Sessions and appointing acting Attorney General Matthew Whitaker.

"I think the Whitaker appointment steps up the timeline, and I think perhaps if Mueller sticks to the strategy of telling us the story through indictments - the indictments speak to us - that he'll speak to us soon, very soon, with additional indictments, perhaps that tell the story of a corrupt president," he said.

The Justice Department said Whitaker will have oversight of Mueller's investigation.

Whitaker has previously expressed that he felt Mueller's investigation is going "too far" in an op-ed he penned for CNN.

"Mueller has come up to a red line in the Russia 2016 election-meddling investigation that he is dangerously close to crossing," Whitaker wrote, calling for Deputy Attorney General Rod Rosenstein to "limit the scope" of the investigation.

On Friday, President Trump said he has not spoken to Whitaker about the Russia investigation.
