Top Justice Department officials are scheduled to interview four candidates Saturday to serve as FBI director on a permanent basis, a source familiar with the process told POLITICO Friday night.

The four potential nominees are: acting FBI Director Andrew McCabe, Sen. John Cornyn (R-Texas), former Justice Department Criminal Division Chief Alice Fisher and New York state judge and former U.S. Attorney in Manhattan Michael Garcia.

Attorney General Jeff Sessions and Deputy Attorney General Rod Rosenstein are expected to conduct the interviews Saturday afternoon, the source said.

Sessions and Rosenstein conducted interviews earlier this week with potential interim FBI directors. That process to find an interim director is still moving forward separately, the source said. Legal requirements limit who can serve in an acting capacity to current Justice Department officials or current Senate-confirmed political appointees.

The FBI chief job is subject to Senate confirmation and carries a 10-year term. James Comey was confirmed to the post in 2013, but was fired Tuesday by President Donald Trump.
