Former Trump campaign adviser George Papadopoulos reportedly lied on his resume about his participation in the Model United Nations.

The Washington Post reported that Papadopoulos claimed he was a “U.S. Representative at the 2012 Geneva International Model United Nations.”

But officials told the Post there isn’t a record of him.

According to newspaper, other information on Papadopoulos’s resume also appears to be untrue.

Papadopoulos said he was a fellow at the Hudson Institute, but officials said he was an unpaid intern and researcher under contract.

Papadopoulos pleaded guilty earlier this month to lying to FBI agents as part of special counsel Robert Mueller’s investigation into Russian meddling in the 2016 presidential election, as well as possible connections between members of President Trump’s campaign and Moscow.

Prosecutors charged Papadopoulos with lying to investigators about his conversations with a foreign professor who told him that Russians had thousands of emails containing “dirt” on Democratic candidate Hillary Clinton.

Trump and the White House have tried to downplay Papadopouolos’s connection to the campaign. Trump said Tuesday on Twitter that he was a “young, low level volunteer” and that he had “already proven to be a liar.”
