WATCH: Intel expert Malcolm Nance predicts Julian Assange will be indicted the same day as Roger Stone

Intelligence expert Malcolm Nance predicted on Wednesday that special counsel Robert Mueller would indict longtime Donald Trump associate Roger Stone at the same time as Wikileaks founder Julian Assange.

Nance, the author of the 2018 book The Plot to Destroy Democracy: How Putin and His Spies Are Undermining America and Dismantling the West, made the prediction on MSNBC's "Hardball" with Chris Matthews.

"We have breaking news tonight from the Washington Post. This suggests special counsel Robert Mueller may have just taken a big step towards indicting Trump's longtime advisor, Roger Stone," Matthews reported.

The host said he's known Stone for thirty to forty years.

"There's no doubt that the master of dark arts in the Trump world is Roger Stone and he's also been his closest political advisor, going back to when he first teased about running for president 20 years ago," Matthews noted. "He does the tricks of politics which are sometimes not so nice."

Nance said that Stone "may have bit off more than he can chew here."

"You know, Bob Mueller's a pretty smart guy himself and I think what he's going to do here, is he is going to build a cage for Roger Stone to jump into and then try to lie his way out of it," he said.

"And he's going to start it off with an indictment," Nance predicted. "I believe Julian Assange himself -- and perhaps the Wikileaks organization -- will be indicted at the exact same time."

"They are the bridge from the Russians to the Trump campaign, through this political dirty tricks team that seems to have been led by Roger Stone," he explained.
