George Nader, reportedly a cooperating witness in Special Counsel Robert Mueller’s investigation into collusion between Donald Trump’s presidential campaign and Russia, was arrested in 1985 on child pornography charges. A frequent visitor to the Trump White House in 2017, Nader is the latest enigmatic character to saunter onto the stage as part of Mueller’s inquiry. A New York Times story last weekend said that Mueller was looking into whether Nader, a Lebanese-American with access to Persian Gulf elites, had helped funnel foreign money toward Trump’s campaign. On Tuesday, the paper said that Nader was cooperating with Mueller’s investigation. The 1985 criminal case against Nader on child pornography charges was eventually dismissed, according to court documents obtained by The Intercept. The existence of the charges was first reported by The Atlantic. “The court found that Mr. Nader’s constitutional rights had been flagrantly violated, and the case was thrown out in its entirety before trial,” a representative for Nader told The Intercept. “Mr. Nader vigorously denies the allegations now, as he did then.”

According to prosecutors, as relayed in the U.S. District Court judge’s ruling on a motion to suppress evidence in the case, Nader received a package that included both a film of young boys engaged in sexual acts and pictures depicting nude boys. Authorities conducted a search based on a warrant, and similar material was found in a room that Nader rented in a Washington home, according to the court documents. The evidence discovered in the home was ruled inadmissible when the warrant was challenged, but the material delivered in the original package was not ruled inadmissible at the time. In July 1986, just ahead of a jury trial, the charges were dismissed, according a docket sheet from the U.S. District Court in Washington. Not all of the court filings are available online, and the reasons for the dismissal were not immediately clear.
