In an effort to simplify, we’ve created the following timeline, which places information about interactions between the Trump team and Russia in the proper chronological order. We’ve included the dates on which each piece of information was reported to give a sense of when the revelations were made. (Those dates are indicated in parentheses after each piece of information.) Significant figures in the investigations are indicated in bold.

I think you’re going to find it very informative and very, very interesting.”

June 9

Trump Jr., Manafort and Kushner meet at Trump Tower with a Kremlin-connected attorney named Natalia Veselnitskaya. Veselnitskaya’s efforts to reverse a law passed in 2012 sanctioning Russians suspected of human rights violations at some point drew the attention of the FBI. The meeting was not initially reported to the government by Kushner as required when he took a position with the administration.

In a private meeting with Russian Foreign Minister Sergey Lavrov and Kislyak, Trump reveals classified information shared with the United States by an ally, later reported to be Israel.
