The US senate has confirmed that Christopher Wray will lead the FBI, replacing James Comey, who was dismissed from his position in May.
The senate voted 92-5 in favour of Mr Wray, who was US President Donald Trump's choice for the role of FBI director.
Mr Comey was fired by Mr Trump amid an investigation into Russia's interference in the 2016 presidential election, leaving the bureau in a state of flux.
During the Senate debate of Mr Wray's nomination, Senator Amy Klobuchar said: "This is a tough time to take this tough job. The previous FBI director, as we know, was fired because of the Russia investigation.
"The former acting attorney general was fired. And we've had a slew of other firings throughout the government over the last few months."
Mr Wray, 50, was formerly a high-ranking official in President George W Bush's Justice Department and won unanimous support from the Senate Judiciary Committee last month.
He has said he is committed to keeping politics out of the FBI's operations.
"My loyalty is to the Constitution and the rule of law. Those have been my guideposts throughout my career, and I will continue to adhere to them no matter the test," Wray said at his confirmation hearing.
