Former FBI Director James Comey is set to testify before the Senate Intelligence Committee on Thursday about Russian involvement in the 2016 presidential election — and his interactions with President Donald Trump with regards to the matter.

Below is a timeline of developments between Comey, Trump and the investigation into Russia's involvement.

Jan. 6: The intel community details that Russia interfered in the 2016 election — to hurt Hillary Clinton and benefit Trump. Comey also tells Trump that the FBI doesn’t have an open counter-intelligence case on him individually, according to Comey’s statement released ahead of his Thursday Senate hearing.

Jan. 27: Trump has dinner with Comey, telling the FBI director: “I need loyalty, I expect loyalty,” per Comey’s June 7 statement.

Feb. 14: Comey meets with Trump at the White House, where the president tells the FBI director: "I hope you can see your way clear to letting this go, to letting Flynn go," according to a memo Comey wrote about the meeting.
