Attorney General Jeff Sessions on Tuesday shot down accusations from a Senate Democrat that there is some secret reason why he recused himself from the federal investigation into Russian meddling in the 2016 election.

Sen. Ron Wyden, D-Ore., pressed Sessions in a Senate Intelligence Committee hearing for more information about what former FBI Director James Comey meant last week when he said there was something about Sessions' connections to Russia that are "problematic."

"Mr. Comey said there were matters with respect to the recusal that were problematic and he couldn't talk about them," Wyden said. "What are they?"

"Why don't you tell me?" Sessions fired back. "There are none, Sen. Wyden. There are none. I can tell you that for absolutely certainty."

"This is a secret innuendo being leaked out there about me, and I don't appreciate it, and I tried to give my best and truthful answers to any committee I've appeared before," he said.

After Comey said in public that something about Sessions's background was "problematic" and required his recusal from the Russia investigation, he reportedly told senators in a closed-door session that Sessions may have had a third, unreported meeting with Russian Ambassador Sergei Kislyak.

But Sessions dismissed that charge in his testimony, and said that while he may have been at the same event with Kislyak in April of 2016, he did not have any direct contact with Kislyak.
