Two men who sought to advance allegations relating to the late Democratic National Committee (DNC) staffer Seth Rich have retracted their claims and apologized to Rich's family.
Rich was shot and killed in Washington in 2016, in what police have said was an apparent botched robbery.
Butowsky on Jan. 13 backed away from claims that Aaron Rich, Seth Rich's brother, was involved in transferring DNC files to WikiLeaks.
"I never had physical proof to back up any such statements or suggestions, which I now acknowledge I should not have made," he said. "I take full responsibility for my comments and I apologize for any pain I have caused. I sincerely hope the Rich family is able to find out who murdered their son and bring this tragic chapter in their lives to a close."
Butowsky later deleted the statement.
Butowsky, a wealth manager formerly with Morgan Stanley, had frequently appeared on cable television and gave interviews to a range of outlets. He was sued by Aaron Rich for defamation.
According to the lawsuit, Butowsky contacted the Rich family in early 2017 and offered to fund the hiring of a former Washington police investigator to lead a private investigation into the slaying.
Butowsky then pushed Fox News to publish a story about the homicide, which quoted Wheeler as having discovered proof that Seth Rich had leaked DNC documents to WikiLeaks. Butowsky was also the only listed source for a Washington Times article detailing "cover-up questions" about Seth and Aaron Rich.
Matt Couch, the founder of the now-dissolved America First Media, also promoted allegations that Seth Rich was the source of DNC documents that WikiLeaks published and that Aaron Rich was involved, the suit said.
"Today, we retract and disavow our statements, and [we offer] our apology to Mr. Rich and his family."
Couch has said before that the information he published about Aaron Rich and Wikileaks was sourced from Butowsky.
In response to the retractions, Aaron Rich told news outlets: “In the more than four years since we lost Seth, the accusations made against our family have only served to prolong our grief without bringing us any closer to finding Seth’s murderer.
"Although we will never be at peace until we obtain justice for Seth’s murder, I hope that these events may encourage others to pause and consider the impact of accusing strangers of wrongdoing, give law enforcement space to do their jobs, and let us remember Seth in peace and with privacy."
A flurry of lawsuits relating to claims about Seth Rich's family have been filed, both against people and outlets who promoted certain claims about the homicide and against reporters and media outlets who reported on those who promoted the claims. Butowsky sued several outlets for their reporting on him, but they were all dismissed voluntarily or by a judge.
The allegations center around the source of DNC documents that Wikileaks posted in 2016. The DNC-hired CrowdStrike firm has blamed Russian hackers, as did the FBI, although the agency relied on CrowdStrike's analysis and didn't examine the servers itself.
WikiLeaks founder Julian Assange has suggested he obtained the documents from Rich, whose death remains unsolved.
The serials "make brief references to Seth Rich but is voluminous due to the nature of the material (including an image of Seth Rich's personal laptop)," the bureau wrote. It was granted a three-month extension to properly sift through the files.
