A prominent conservative legal analyst told Fox News that major developments are imminent in the investigations into President Donald Trump and his 2016 campaign.

Former Judge Andrew Napolitano was asked by Fox News host Shepard Smith whether he found the silence to be deafening.

"To me it is, yes, it means something is coming," Judge Napolitano suggested.

Napolitano offered a historical analogy for understanding the broadening investigation.

"With Clinton, it started out with the land deal and ended up with a blue dress," Napolitano reminded.

"Now they're on to why was Michael Flynn fired," Napolitano suggested. "Was it for a corrupt purpose or was it for a noble purpose?"

The question of whether on not Michael Flynn lied to the FBI could have major repercussions on whether Flynn will "flip" and turn state's evidence.

"A lot of us believe when the FBI interrogated General Flynn, they had in front of him a transcript of his conversation with the ambassador and he didn't know it and he did not recount the same conversation that they knew took place," Napolitano suggested. "Is that a lie? A crime? Should he be indicted for it? If he's indicted, will he become a cooperating witness?

Investigators, "may decide somebody is going to get indicted and once we indict that person, we're going to ask them to testify against someone north of them on the totem poll," Napolitano explained earlier in the show. "That's the way federal investigations are conducted all of the country today."

Napolitano also tried to clarify the nature of the criminal investigations involving President Trump.

"I suggest to you it's a technical definition of words, so i'm going to cut to the chase," Napolitano said. "The President is the subject of a criminal investigation, he is not the target of a criminal investigation."

"Target means they plan to seek your indictment. They can't indict the President for what he did while he's President," Napolitano reminded. "They can only send it to the House Judiciary Committee for impeachment."

"Can they investigate him? Of course they can and they are."
