Four candidates to replace James Comey as FBI director are set to be interviewed by US Attorney General Jeff Sessions.
Among those expected at the Justice Department on Saturday are acting FBI director Andrew McCabe and Alice Fisher, a top Justice Department official in the George W Bush administration.
The list of interviewees is also said to include Michael Garcia, an associate judge on New York's highest court, and Republican Senator John Cornyn of Texas, the deputy Senate leader and a former state attorney general.
The four are among nearly a dozen candidates Mr Trump is considering, a group that includes several lawmakers, attorneys and law enforcement officials.
Ms Fisher formerly served as assistant attorney general for the Justice Department's Criminal Division.
She faced resistance from Democrats during her confirmation over her alleged participation in discussions about detention policies at the Guantanamo Bay facility in Cuba.
She also was deputy special counsel to the Senate special committee that investigated President Bill Clinton's Whitewater scandal.
The FBI has never had a female director.
