Berkeley Heights, New Jersey (CNN) The President's eldest son Donald Trump Jr. downplayed Monday a 2016 meeting between top campaign aides to his father and a Russian lawyer, saying the highly scrutinized engagement "ended up being about essentially nothing that was relevant" to questions of collusion.

The remarks, which came during a friendly interview on The Laura Ingraham Show, came after President Donald Trump wrote on Twitter the June 2016 meeting was intended to get damaging information on his Democratic opponent Hillary Clinton — contradicting a statement he dictated when the meeting came to light a year ago

In the interview Monday, Trump Jr. said the session lasted 20 minutes, and maintained the central focus was on adoptions — even as he conceded the Clinton dirt was how the Russian lawyers secured the meeting in the first place.
