Watch: MSNBC panel takes hilarious turn as angry Republican insists Trump has read the Federalist Papers

A debate about whether Trump can be indicted for treason, money laundering, fraud or any other serious crime while still in office went off the rails on MSNBC Thursday afternoon.

Ari Melber moderated the debate between Madison Gesiotto, a former figure skater turned rabid Trump defender, and Dr. Christina Greer, a fellow at New York University.

Gesiotto came out firing off legal terms like "dispositive evidence," making the argument that Trump couldn't be tried because he's the president.

"If we were to indict a sitting president—any sitting president, not just Trump, that would essentially give a jury of only 12 people the ability to essentially overturn a national election," she said. "And that's a pretty scary thing."

Greer came right back firing about what the framers envisioned. Which, she conceded, was for Congress to be a check against his authority.

"They're acting like a bunch of sycophants," she said. "And we've never seen a president like Trump... we've never had a president who's been this disrespectful to the office."

Things really heated up when Greer referred to the U.S. Constitution as a rough draft," prompting Gesiotto to freak out.

"They never thought they would have a president in the mold of Donald Trump," Greer said. "We are supposed to elect a president who puts the country first."

Greer then pointed out that Trump is only semi-literate—which Gesiotto angrily replied to by claiming that Trump has read not only the Constitution, but the Federalist papers.

"He doesn't read," Greer said.

"He's read the Constitution," Gesiotto claimed. "He has also read Federalist paper number 69, by Alexander Hamilton."
