"Dershowitz plans to argue on the Senate floor that "even if everything that is alleged by the House managers is proven or taken as true, they would not rise to the level of an impeachable offense."
"If my argument succeeds, there's no need for witnesses. Indeed, there's no need for even arguments, any further arguments. If the House charges do not include impeachable offenses, that's really the end of the matter, and the Senate should vote to acquit, or even to dismiss," Dershowitz said."
"He said it didn't matter whether he thought what Trump did was acceptable, only if it was impeachable."
House Intelligence Committee Chairman Adam Schiff, D-Calif., the lead impeachment manager, called Dershowitz's argument that abuse of power is not impeachable "absurdist."
"That's the argument I suppose you have to make if the facts are so dead set against you," Schiff said on "This Week."
"You have to rely on an argument that even if he abused his office in this horrendous way, that it's not impeachable," Schiff said. "You had to go so far out of the mainstream to find someone to make that argument, you had to leave the realm of constitutional law scholars and go to criminal defense lawyers."
Schiff said "the mere idea" of Dershowitz's argument would have "appalled the founders," who were very concerned about foreign election interference. He argued that such action goes to "the very heart of what the framers intended to be impeachable."
"The logic of that absurdist position that's being now adopted by the president is he could give away the state of Alaska," Schiff said. "He could withhold execution of sanctions on Russia for interfering in the last election, to induce or coerce Russia to interfere in the next one." excerpts
