“I think this is probably the tip of a prosecutorial iceberg, so to speak,” Napolitano said Friday on Fox News. “It is a nightmare for Donald Trump.

Napolitano's comments come after former national security adviser Michael Flynn pleaded guilty to lying to FBI officials about his contacts with Russian officials.

As part of the plea agreement, Flynn is cooperating with special counsel Robert Mueller's probe into Russian meddling in the 2016 presidential election. Prosecutors said that a very senior member of the president's transition team "directed" Flynn to contact Russian officials.
