Harvard Law School professor emeritus Alan Dershowitz criticized House Democrats on Wednesday for voting to hold former White House chief of staff Mark Meadows in contempt of Congress before courts had ruled on his privilege claims.

Meadows had been subpoenaed to provide evidence to the January 6 committee, and handed over some documents before withholding others that former President Donald Trump has said are covered by executive privilege and cannot be used.

The questions of whether executive privilege by a former president can still apply, and what the limits of executive privilege are, remain unresolved, and both Meadows and former Trump adviser Stephen K. Bannon have asked the courts to rule.
