Mueller and his team were tasked with investigating accusations of President Donald Trump’s “collusion” with Russia during the 2016 election, but found no evidence of it. In their final report they tried to insinuate that Trump was guilty of obstruction of justice, but stopped short of outright saying so.

An 87-page document, released by the Justice Department on Thursday under the Freedom of Information Act, reveals that Mueller’s investigators “accidentally” or deliberately wiping their devices when the DOJ inspector-general asked for them.

At least 12 officials, whose names are redacted, claimed to have accidentally erased all data from their phones. Five officials are mentioned by name: Andrew Weissman, James Quarles, Greg Andre, Kyle Freeny and Rush Atkinson. Their phones allegedly wiped themselves or reset after too many wrong password entries.

As many as 31 phones may have been affected, including the devices that had been “reassigned.”

Weissman was Mueller’s principal deputy. He is generally considered to have actually been in charge of the ‘Russiagate’ probe, especially after the former FBI director couldn’t recall much of anything during his July 2019 testimony before Congress.

Another discovery in the document was that the phone belonging to FBI lawyer Lisa Page got “lost” by the Mueller team, and the name of the official who had custody of it: Christopher Greer. It was eventually retrieved, but the IG report found that it had been wiped two weeks after Page had left the special counsel team.

Page was involved both in the early stages of the special counsel investigation and the original ‘Crossfire Hurricane’ probe of the Trump campaign – alongside Agent Peter Strzok, with whom she had an extramarital romantic relationship. Both were quietly removed from Mueller’s team after the discovery of text messages that disparaged Trump voters and even referred to “stopping” his election via an “insurance policy.”
