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.
