Story highlights Wednesday's hearing was slated five weeks ago but the guest list has high profile witnesses

Scheduled to speak: Dan Coats, Mike Rogers, Andrew McCabe and Rod Rosenstein

Washington (CNN) The Senate intelligence committee is back in the national spotlight for two days of blockbuster hearings and following news that relations between President Donald Trump and Attorney General Jeff Sessions had reached a boiling point surrounding his recusal from the Justice Department's Russia investigation.

Before Senate investigators probe former FBI Director James Comey , they will press four intelligence officials Wednesday in a hearing that on any other week would be the biggest event on Capitol Hill.

Director of National Intelligence Dan Coats, National Security Agency Director Adm. Mike Rogers, acting FBI Director Andrew McCabe and Deputy Attorney General Rod Rosenstein will all testify before the Senate intelligence committee 24 hours before the Comey hearing.

The event was scheduled five weeks ago as a review of the Foreign Intelligence Surveillance Act, but it quickly morphed into another chance for lawmakers to get some answers on the Justice Department's investigation into President Donald Trump's campaign and Russian meddling in the US election.

The hearing also comes the morning after news broke that Trump and Sessions have had a series of heated exchanges in the last several weeks, after Sessions recused himself from the Russia probe, according to a source close to Sessions.
