Attorney General Jeff Sessions heads to Capitol Hill Tuesday morning to face congressional investigators amid new evidence of Russian collusion in the 2016 presidential election.
The former Alabama senator will be questioned by the House Judiciary Committee regarding just how much he knew about alleged Russian contacts’ involvement with the Trump campaign.
The appearance comes after the FBI revealed a former Trump campaign aide pleaded guilty to making false statements to the intelligence arm. And another former adviser recently testified that Sessions, 70, knew about a trip he took to Russia during the campaign.
Read on for a timeline of Sessions’ involvement with President Trump’s campaign and the Russia election.

April 27, 2016 – Reports suggest Sessions may have had a private meeting with Russia’s then-ambassador to the U.S., Sergey Kislyak at the Mayflower Hotel in Washington, D.C.
Sessions later denies having any private meetings while at the hotel for Trump’s speech.

January, 10 2017 – Sen. Al Franken, D-Minn., asks Sessions if he knows of any communication between the Russian government and the Trump campaign during his confirmation hearing for attorney general.
“I’m not aware of any of those activities. I have been called a surrogate at a time or two in that campaign and I didn’t have – did not have communications with the Russians, and I’m unable to comment on it,” Sessions says.
January 17, 2017 – Sen. Patrick Leahy, D-Vt., submits written questions for Sessions to answer, which includes the question, “Have you been in contact with anyone connected to any part of the Russian government about the 2016 election, either before or after Election Day?”
