Director of National Intelligence Dan Coats, Acting FBI Director Andrew McCabe, National Security Agency Director Mike Rogers and Deputy U.S. Attorney General Rod Rosenstein will appear before the Senate Intelligence Committee in both open public and closed-door hearings on Wednesday to discuss the Foreign Intelligence Surveillance Act, or FISA, the committee said in a statement.

A part of FISA known as Section 702 will expire on Dec. 31 unless Congress votes to reauthorize it.
