With Deputy Attorney General Rod Rosenstein testifying before the Senate Intelligence Committee today and Comey himself to do so tomorrow, the survey finds the public taking a particularly dim view of Trump in the controversy. Sixty-one percent say he ditched the director to protect himself; just 27 percent think he did it for the good of the nation.

Fifty-six percent also think Trump is trying to interfere with investigations into possible Russian interference in the election, while just a third think he’s cooperating. And 72 percent report just some or no trust in what Trump says about the issue – half, none at all. Just 21 percent report a great deal or good amount of trust in what the president says about it.

Even conservatives are about twice as apt to have low trust in what Trump says about Russian interference than to have substantial trust, 60-33 percent. And in the president’s own party, Republicans split evenly on the question of trust, 48 percent expressing distrust, 45 percent, trust.
