The top Democrat on the House Intelligence Committee wants Jared Kushner to come before lawmakers to talk about his dealings with Russian diplomats over a proposed backchannel line of communication.

Rep. Adam Schiff, D-Calif., said on ABC Sunday Kushner needs to face questioning over his talks with Russian Ambassador Sergey Kislyak before President Trump took office. According to a Washington Post report, Kushner met with Kislyak about setting up a backchannel line of communication with the Kremlin for when Trump came into the White House.

Schiff said Kushner needs to answer questions about his motivations and he must be questioned over whether he disclosed the conversations while applying for a security clearance.

"We're going to want Mr. Kushner to come before our committee, I fully expect that will happen," Schiff said.

He added, "If these allegations are true and he had discussions with the Russians about establishing a backchannel and he didn't reveal that, that's a real problem in terms of whether he should maintain that security clearance."

Kushner is Trump's son-in-law and one of his closest advisers. The former real estate scion became one of Trump's top aides during the campaign and is one of the few people the president trusts.

Kushner reportedly wanted to meet with the Russians in their facilities in order to keep out of the American public eye, according to the Post report. Schiff said this raises many questions about his motivations.

"For people associated with the campaign after that campaign has ended, and where the Russians during that campaign were helping you, to try and establish a backchannel (is troubling)," Schiff said.
