Former FBI chief Robert S Mueller III passed away on Friday at the age of 81. His family asked for privacy as they mourned his loss.
Mueller, who served as FBI director from 2001 to 2013, is widely credited with transforming the agency into a more effective counterterrorism force.
He later served as special counsel from 2017 to 2019, leading the Justice Department's investigation into Russian interference in the 2016 U.S. presidential election and potential coordination with Donald Trump's campaign.
Trump reacted to Mueller's death on Truth Social, posting, 'Robert Mueller just died. Good, I’m glad he’s dead. He can no longer hurt innocent people!'
The special counsel probe was a persistent source of frustration for Trump throughout his presidency, with him frequently denouncing it as a 'witch hunt' and 'hoax.'
Trump repeatedly accused Mueller of personal bias and conflicts of interest, including claims tied to Mueller's prior relationship with fired FBI Director James Comey.
The Mueller Report, released in redacted form in April 2019, documented multiple instances in which Trump attempted to interfere with or halt the investigation.
