Donald Trump Jr. on Wednesday cited attorney-client privilege to avoid telling lawmakers about a conversation he had with his father, President Donald Trump, after news broke this summer that the younger Trump — and top campaign brass — had met with Russia-connected individuals in Trump Tower during the 2016 campaign.

Though neither Trump Jr. nor the president is an attorney, Trump Jr. told the House Intelligence Committee that there was a lawyer in the room during the discussion, according to the committee’s top Democrat, Rep. Adam Schiff of California. Schiff said he didn’t think it was a legitimate invocation of attorney-client privilege.

“I don’t believe you can shield communications between individuals merely by having an attorney present,” he said, after the committee’s lengthy interview with Trump Jr. “That’s not the purpose of attorney-client privilege.”
