“I think many of us are expecting that [Comey] will say, ‘Yes, the FBI is looking at it.’ That’s what I expect to hear,” Kaine told CNN “New Day” host Chris Cuomo.

Kaine stressed that the investigation must look into whether the White House is connected to Russia.

“When you get to the bottom line of it, we have to understand everything about the ties between Russia, the Trump campaign, the Trump transition and the Trump administration, especially the degree to which Russia tried to invade the American election — because we have to protect future elections,” Kaine continued.

The former Democratic vice presidential nominee suggested this investigation would aid and protect U.S. allies in case Russia also tried to interfere with their elections.

“There’s elections in France coming up, there’s elections in Germany coming up. Russia has already been engaged in the Brexit election. They are engaged in the French election to some degree. We have got to give our allies some idea about how they can protect themselves,” he said, referring to Britain's referendum last year on whether to leave the European Union.
