President Lincoln had asked General Ambrose Burnside to make private inquiries among General McClellan's staff with regards to his ability to lead troops. Burnside was a friend of McClellan's and such a back of the hand stunt did not please Burnside. He followed Lincoln's orders, however. Clearly his top commanders were loyal to McClellan and word got back to him. But Burnside was shocked to learn that not only were McClellan's staff loyal, but worse, in that they held the Lincoln administration in contempt. Burnside was startled to hear open discussions about a military takeover. General in Chief Halleck dismissed Burnside's report as "staff chatter".
