Senate Foreign Relations Chairman Bob Corker said White House senior adviser Jared Kushner is fully cooperating with his committee following a recent report that he tried to set up a backchannel to communicate with the Russians during the transition period.

"Look, I think Jared has said that he's more than willing to answer any and all questions. [The White House] reached out to us yesterday to make sure that we knew that was the case and I'm sure he's willing to do so," Corker told NBC "Meet the Press" host Chuck Todd.

The Tennessee Republican would prefer to see the FBI make a conclusion about Kushner's involvement before President Trump's son-in-law is called to testify on Capitol Hill. He added talking directly with Kushner would "probably be the prudent course of action."

Corker seemed to back Kushner, saying the adviser briefed a bipartisan group of senators on Trump's foreign trip and was received well.

"I've spent a lot of time with Jared... He seems to me to be a very open person and again, I'd let him speak for himself when the time is right on all these issues and at that time we can actually render judgment on the reality of what did or didn't take place," Corker said.

Last December, Kushner and Russian Ambassador Sergey Kislyak discussed using Russian diplomatic facilities in America to keep their talks out of the public eye and to ensure U.S. intelligence officials wouldn't be able to pick up the private chats, the Washington Post reported.

Kushner has been slammed for the proposal by Democrats due to the already-high scrutiny on the Trump camp's relationship with the Kremlin.

The intelligence community has determined the Russian government sought to influence the campaign and developed a preference for Trump over Hillary Clinton. There has been no evidence of collusion between the campaign and the Russian government.
