(CNSNews.com) - Appearing on CNN's "State of the Union" on Sunday, Sen. Dianne Feinstein (D-Calif.), the ranking member of the intelligence committee, was asked about former Trump campaign adviser George Papadopoulos, who boasted of meeting with a foreign professor who said the Russians had "dirt" on Hillary Clinton.



Host Jake Tapper asked Feinstein: "So we learned this week that former Trump foreign policy adviser George Papadopoulos traveled to London in March 2016. And then, in April, he met with a professor who promised dirt on Hillary Clinton from the Russians. Have you seen any evidence that this dirt, these e-mails, were ever given to the Trump campaign?" Tapper asked Feinstein.



"Not so far," Feinstein replied.



Tapper asked Feinstein if she'd ever seen "any communications that suggested that the Trump campaign wanted them (Russians) to release them (emails) through a different means? Because, obviously, they were ultimately released by WikiLeaks."



"No, I have not," Feinstein said.





Tapper also pressed Feinstein on the testimony of Attorney General Jeff Sessions, who told the committee on several occasions he's not aware of any Trump surrogates having communications with the Russians.



But others who worked on the Trump campaign have indicated that Sessions was aware of their contacts with Russians.



Feinstein said Sessions has "got to narrow his recollections. When he comes before the committee again, he has to be precise, and it has to be accurate."



Feinstein said she will asked Chairman Chuck Grassley (R-Iowa) to call Sessions back for another hearing. "He should come back and clarify it," she said.
