News outlets including the Washington Post have retracted or amended reports claiming the FBI warned Giuliani he was the target of a Russian influence operation

• News outlets including the Washington Post retracted a claim about Rudy Giuliani.
• Outlets retracted a claim that the FBI warned Giuliani he was being used to spread Russian disinformation.
• Insider has amended its reporting in the light of the retraction.

The Washington Post and other news outlets have retracted a claim that the FBI warned Rudy Giuliani that he was likely being targetted as part of a Russian disinformation campaign in 2019.

In an editor's note the Post on Saturday said it was retracting a claim in a report Thursday that the FBI had warned both Giuliani and right-wing news network OANN about Russian efforts to use them to spread falsehoods.

It read: "Correction: An earlier version of this story, published Thursday, incorrectly reported that One America News was warned by the FBI that it was the target of a Russian influence operation. That version also said the FBI had provided a similar warning to Rudolph W. Giuliani, which he has since disputed. This version has been corrected to remove assertions that OAN and Giuliani received the warnings."

Insider has amended its report on the claim in light of the retraction in the Post.

The New York Times and NBC News have withdrawn similar claims.

"An earlier version of this article misstated whether Rudolph W. Giuliani received a formal warning from the F.B.I. about Russian disinformation. Mr. Giuliani did not receive such a so-called defensive briefing," reads the correction in the Times.

The reports all focussed on FBI raids on Giuliani's office and apartment in Manhattan last week, in which agents seized computers and other devices belonging to Giuliani.

Investigators are reportedly probing whether Giuliani was acting on behalf of Ukrainian officials during his search for damaging information about Joe Biden, then Democratic presidential nominee, and his son, Hunter, in Ukraine in 2019.

The Times reported that Giuliani's communications with the Trump administration over the firing of the US ambassador to Ukraine, Marie Yovanovitch, in May 2019 were being scrutinised the federal agents.

Giuliani has denied any wrongdoing.

"I've never represented a Ukrainian national or official before the United States government," Giuliani said in an interview on Fox News on Thursday in the wake of the raids.
