Conspiracy Theorist Jerome Corsi Says Mueller Subpoenaed His Stepson to Testify in Russia Probe

Conspiracy theorist Jerome Corsi claimed Monday that his stepson had received a subpoena to testify in the Russia probe led by special counsel Robert Mueller.

Speaking on Fox Business Network, the conservative writer claimed Andrew Stettner was summoned over text messages that claimed a computer in Corsi's office had been "scrubbed."

Corsi said that Stettner wiped the computer so that he could use it for his mother's business. "I think they think that Andrew was conspiring with me, as my computer expert, to destroy evidence," he said Monday. "They're looking for anything they can find."

Corsi himself was subpoenaed for grand jury testimony last year. At the time, he said he was likely summoned over communications with close ally of President Donald Trump and lobbyist Roger Stone.

Draft court documents, The Washington Post reported, claim Corsi exchanged emails with Stone—which have since been deleted— concerning data released by the whistleblower website Wikileaks before the 2016 election.

The inflammatory author of books such as Killing the Deep State: The Fight to Save President Trump and Where's the Birth Certificate? The Case That Barack Obama Is Not Eligible to Be President frequently attacks the Mueller probe, claiming it is intruding into the lives of his family.

Before Monday's television appearance, the former InfoWars Washington, D.C. bureau chief shared a video via Twitter asking Robert Mueller to "leave [his] family alone." The two-minute video features statements including, "You've sunk to a new low: intimidating my children," and "These are Gestapo intimidation tactics," intercut with unflattering images of Mueller and stock photos of empty pockets and attack dogs. Dramatic instrumental music plays throughout.

"We Italians cherish our families, and we protect our own," the video says. "We've seen mafia types like you before."

An avid Trump supporter, it's unclear if Corsi was aware of the president's possible links to the mafia, detailed in a recent Newsweek report.

Corsi filed a lawsuit against Mueller in December alleging illegal surveillance. In November, he set up a crowdfunding page to support his legal expenses and "help his family in the event he is incarcerated by Mueller." As of 9.30 a.m. ET January 15, the page had raised just over 10 percent of its $250,000 goal.
