Fox News senior judicial analyst Andrew Napolitano appeared on Fox & Friends Tuesday and laid out what it would take for Special Counsel Robert Mueller‘s investigation to find crimes stemming from the Trump Tower meeting.

The June 2016 meeting at Trump Tower — at which Don Jr. and other Trump campaign staffers met with a Kremlin-tied lawyer promising dirt on Hillary Clinton — is back in the news this week after the president admitted the meeting was not primarily about adoptions, as previously claimed.

Fox & Friends host Steve Doocy asked Napolitano: “Is it against the law, if you’re in politics, to try and dig up dirt on your opponent?”

“No of course not, and everybody does it, and to that extent the president’s correct,” Napolitano said. “But…”

“There are federal statutes that prohibit receiving something of value from a foreign national, foreign entity, or foreign government,” he continued. “So was the purpose of this meeting to receive something of value? That’s something Bob Mueller’s going to have to look at.”

“Is there a crime here, or conspiracy?” Ainsley Earhardt asked.

“I don’t know the answer to that. But unfortunately, a lot of these statutes are written to make it easier for the government to convict,” Napolitano replied. “So if there was an agreement to receive dirt on Hillary, from the Russians, even if the dirt never came, if those who agreed, at least one of them, took some step in furtherance of the agreement, then there is the potential crime for conspiracy.”
