"Jeff, you need to tell us everything you know about Russia. So yeah, he probably should come back, and answer the question yet again 'did you know anything about an effort by the Trump campaign to meet with Russia, not just collude with Russia,' " Graham told Chris Wallace on "Fox News Sunday," issuing a direct appeal to the attorney general.

"This is getting a bit old with Jeff Sessions," he continued.

"I asked a question 'did anyone ever talk to you about talking with the Russians?' I didn't ask about collusions. So we now know that somebody at a meeting, Mr. Papadopoulos, raised the idea of meeting with Putin. There's nothing wrong with Trump meeting with Putin if he wanted to. It would be wrong to have the Russians help the Trump campaign," he said.

Graham's comments come after The New York Times reported that unsealed court documents revealed that Trump and Sessions were aware of correspondence between members of the campaign and Russian actors, despite saying earlier this year they were unaware of such communications.

The documents show that former Trump campaign adviser George Papadopoulos floated the idea of meeting with the Russian ambassador in London, during a meeting in which he claims Trump and Sessions were present.

Sessions told the Judiciary Committee earlier this year that he was unaware of any contact between the Trump campaign and Russians.

Democratic lawmakers have also called for Sessions to return to testify before the Judiciary Committee.
