From the Washington Times:

Alan Dershowitz, who is part of President Trump’s impeachment legal defense team, said Sunday that even if the House managers successfully laid out the facts in their case they would still fall short of the standard needed to impeach and remove Mr. Trump from office.

He said abuse of power and obstruction of Congress, which are the charges Mr. Trump stands accused of, are “vague, open-ended” criteria.

“Even if the factual allegations are true – which are highly disputed and which the defense team will show contrary evidence – but even if true, they did not allege impeachable offenses,” Mr. Dershowitz said on “Fox News Sunday.” “So there can’t be a constitutionally authorized impeachment.”
