Graham took down Napolitano’s claim that Trump was guilty of obstruction of justice while on Fox News. Graham told the network “he completely 100% wrong. The obstruction of justice pertains to colluding with the Russians, not firing Comey. The theory is that you fire Comey to stop the Russian investigation. What do we know after the Mueller report? There was no collusion between the Trump campaign and the Russians. There is no underlying crime.”. He was applauded for his remarks on social media after Napalitano’s flawed argument did not go over well.
