A key witness who testified in an official investigation into Russian interference during the 2016 general election admitted guilt in a child sex lawsuit in Virginia, on Jan. 13.

George Nader has pleaded guilty to committing child sex trafficking and child pornography offenses at the federal court in Alexandria, 10 miles south of Washington.

The political lobbyist and Lebanese-American businessman confirmed he transported a 14-year-old male from the Czech Republic to Washington to engage in a sexual act with him back in the year 2000. Nader, 60, also said he had child pornography including explicit images of children who were either infants or toddlers according to Fox News.

The broadcaster revealed he could face a mandatory minimum sentence of 10 years in jail. Prosecutors are widely expected to recommend Nader only serves the minimum time because they made a plea bargain with him earlier on.

However, the judge will have the final decision on whether to hand down a longer sentence on April 10 according to The Associated Press. There is potential for the sentence to be as long as 30 years depending on the outcome of the court case.

The news agency has counted Nader’s name more than 100 times in former Federal Bureau of Investigation Robert Mueller’s final report on the Russian interference probe. The accused allegedly served as liaison between a Russian banker linked to Russian President Vladimir Putin and members of President Donald Trump’s transition team back in early 2017.

Nader is separately facing seven more charges for conspiring to hide the source of more than $3.5 million in political donations to support then Democratic presidential candidate Hillary Clinton’s 2016 bid for the Oval Office. In that case prosecutors believe he tried to win praise from Clinton through reporting to an anonymous Middle Eastern government on that operation.

Nader previously worked as an adviser to the United Arab Emirates, and allegedly used a company based in Canada to perform a wire transfer totaling $2.5 million to major Trump fundraiser Elliott Broidy. Fox News speculates the money was intended to convince the United States to adopt a more hard-line stance against Qatar, which has experienced a rocky relationship with the United Arab Emirates.

In the Czech Republic he was earlier convicted in 10 child sex abuse cases. Nader allegedly found his teenage male victim at an arcade in the capitol Prague and promised “money, jewelry, mobile telephones, clothing, care, and housing” in exchange for sexual favors. He received a one-year jail sentence in the year 2003.
