The top lawmakers on the Senate Intelligence Committee said Wednesday they met with the man overseeing the Department of Justice's Russia investigation and called the session "constructive."

Committee chairman Sen. Richard Burr, R-N.C., and vice chairman Mark Warner, D-Va., released a brief joint statement about their meeting with Robert Mueller, a former FBI director who is now tasked with leading the Russia probe.

"We had a constructive meeting with the special counsel today and we look forward to future engagements," the pair said.

In an interview with CNN after the meeting, Burr added, "I don't think it's necessary for us to meet [again]. I think we'll be in communication personally with him on any aspects that might bleed over from one to the other."

Mueller's successor at the FBI James Comey answered questions from the Senate Intelligence Committee last week about his firing, the Russia investigation, and even the Hillary Clinton email probe. This week, Assistant Attorney General Rod Rosenstein and Attorney General Jeff Sessions faced questions from the same panel.

Mueller has not yet made any public statements about the investigation he is now tasked with spearheading.
