Tempers flared during an exchange between Attorney General Jeff Sessions and Sen. Ron Wyden (D) on Tuesday as the Oregon senator quoted former FBI Director James Comey as saying Sessions' involvement in the Russia probe was "problematic."

Wyden additionally expressed frustration at Sessions' "stonewalling" of the American people by keeping certain parts of testimony private from them. "Senator Wyden, I am not stonewalling," Sessions snapped, before adding he had recused himself from the Russia probe his first day in office.

"General Sessions, respectfully, you're not answering the question," Wyden interjected, pushing for Sessions to explain what "problematic" questions Comey might have had.

Sessions, raising his voice, shot back: "Why don't you tell me? There are none, Senator Wyden. There are none. I can tell you that for absolute certainty." Watch the fiery exchange below. Jeva Lange
