To answer your question perhaps Wyden did not advocate this because there wasn't enough support or votes in the Senate. Things have changed in the last month. Dems have a stronger majority in Congress and a democratic president.
Sorry, but this doesn't make any sense. Why, with an increased/stronger Democratic majority and President, would they now have to advocate a weaker anti-torture law than what they were advocating before, when they had fewer seats and a GOP President?
