Former FBI Director Robert Mueller has died at the age of 81, according to a family statement cited by US media. Reports said he passed away late Friday night, though the location and cause of death were not disclosed. Former President Donald Trump reacted on his social media platform, writing that Mueller’s death meant he could no longer harm innocent people, AFP reported from Washington.

Mueller served as FBI Director for 12 years, beginning just days before the September 11, 2001, attacks. He strengthened the agency’s counterterrorism operations and later became special counsel for the US Department of Justice to investigate possible Russian interference in Trump’s 2016 campaign. His two-year investigation led to charges against 34 individuals and three entities, including six of Trump’s associates.

Before the politically sensitive Russia probe, Mueller had a strong reputation in Washington, having served under both Democratic and Republican presidents. A decorated Vietnam War veteran and former Marine, he was known for his professionalism and strict work ethic, earning respect across party lines.
