Donald Trump Jr. shared Thursday a tweet linking former President Bill Clinton's 1993 firing of the FBI director to the death of Clinton aide Vince Foster, alluding to a far-right conspiracy theory.
"President Clinton fired his FBI director on July 19th, 1993, the day before Vince Foster was found dead in Marcy Park," the tweet said.
The supposed connection between Clinton's ousting of the FBI director and the death of his aide has long been a conspiracy theory popular among some Republicans, with the implication that Clinton was somehow involved in Foster's death.
CNN first reported Trump's retweet.
President Trump commented on the conspiracy during his 2016 campaign, referring to Foster's death as "very fishy."
Several investigations, however, have ruled that the death was a suicide.
President Trump's decision to fire the FBI Director James Comey this week sparked a wave of criticism and backlash from the Democrats who questioned the timing of the decision.
Reports suggest that Trump was angry at Comey over the FBI investigation into possible connections between Trump's campaign and Russia.
