The top Democrat on the House Intelligence Committee said he will want to question Donald Trump Jr. after news came out that the President’s son met with a Kremlin-linked lawyer last June.

Rep. Adam Schiff (D-CA) said on CNN on Sunday that the meeting raises “a variety of questions” because Trump has denied having any kind of meetings like this.

“They claimed this meeting had nothing to do with the campaign, and yet the Trump campaign manager is invited to come to the meeting and there’s no reason for this Russian government advocate to be meeting with Paul Manafort or Mr. Kushner or the President’s son if it wasn’t about the campaign and Russia policy,” he said.

He said the meeting is indicative of the fact that Russia was “obviously” trying to “influence one of the candidates” and that the explanations given from the administration so far don’t “make sense.” He said his committee would like to “get to the bottom” of what happened at the meeting and he plans to question everyone who was at the meeting.

“By trying to frame this about adoptions ignores what it sounds like the meeting might have been about and that was the Magnitsky Act, which is legislation, very powerful sanctions legislation, that goes against Russian human rights abusers,” he said.

“So if this was an effort to do away with that sanctions policy, that is obviously very significant that the President’s team, then-candidate Trump’s team, that contradicts of course what the President and his people have said about whether they’ve been meeting with any members of the Russian government,” he said.
