Comey declined an invitation to speak to the Senate Intelligence Committee in a closed door session next week, according to The Hill.

However, The New York Times reports that Comey is willing to speak if it's a public hearing. 

Comey was the face of the FBI throughout the investigation into Russia's interference in the 2016 presidential election and alleged coordination with President Trump's campaign. He was fired by Trump on Tuesday in a surprise move that sparked criticism and confusion throughout Washington.
