President Trump tweeted Sunday morning about the now-infamous June 9, 2016 meeting at Trump Tower between Russians and Trump campaign officials, including his son, Donald Trump Jr.

"Fake News reporting, a complete fabrication, that I am concerned about the meeting my wonderful son, Donald, had in Trump Tower. This was a meeting to get information on an opponent, totally legal and done all the time in politics - and it went nowhere. I did not know about it!"

Why it matters: Trump and his son have repeatedly changed their stance on the purpose of the 2016 meeting. In a statement to The New York Times last July, which investigators now know was dictated by President Trump, Don Jr. said the meeting was primarily about Russian adoptions. Trump's former lawyer Michael Cohen has also claimed that the president approved the meeting ahead of time, contradicting continued denials by Trump and his legal team.
