Judge Andrew Napolitano predicted that the special counsel's charges today against former Trump campaign manager Paul Manafort is the "first of many steps" in the Russia probe.

"This is the first of many dominoes to fall," the judge told "America's Newsroom."

Manafort turned himself in to the Washington, D.C. FBI office this morning on charges including conspiracy against the United States and money laundering in Russia-related business deals.

"What is troubling and newsworthy is the allegations continue to September of 2016, meaning during the time that Paul Manafort was the chair ... of Donald Trump's campaign," Napolitano said.

"You're going to indict people going up the totem pole to see if you can squeeze them," he said of Special Counsel Robert Mueller's strategy.

"Sometimes people will make things up so that the squeezing will stop," the judge said. "Sometimes they'll say, 'I don't know anything about the president.'"

Manafort and his business associate and fellow campaign official Rick Gates are the first to be charged in the Russia collusion probe.
