According to Knewz, Trump’s former presidential campaign chair was removed from a flight at Miami International Airport on March 20. The Customs and Border Protection unit at the airport reportedly denied his ability to travel due to an undisclosed problem with his passport.

The Associated Press confirmed the news published by Knewz, reporting that the removal of Manafort from the Emirates Airlines flight occurred without incident or resistance. It is unknown who else was with Manafort at the time or why he was traveling to Dubai.

Manafort pleaded guilty in 2018 to charges of conspiracy, fraud and tax evasion. The charges came after they were declassified by Robert Mueller in his investigation into potential ties between the Trump presidential campaign and Russian officials.

Among his dealings were those involving Konstantin Kilimnik, a political consultant with both Russian and Ukrainian ties. Manafort was accused of and subsequently pleaded guilty to lying about his relationship with Kilimnik and how he shared “sensitive campaign polling data” with him, according to the Mueller Report.

Newsweek reached out to representatives of Manafort for comment but has not received a response. The airport referred Newsweek to the border protection unit. Emirates Airlines refused to provide a statement.

“For privacy reasons, U.S. Customs and Border Protection is unable to discuss a specific individual’s arrival or departure into or from the United States,” a spokesperson for U.S. Customs and Border Protection unit told Newsweek.

After his plea and trial, Manafort was sentenced to 7 1/2 years in prison. Trump gave him a “full and complete” pardon in December of 2020. The pardon came only a few months after Manafort was released from prison into house arrest due to concerns surrounding the spread of COVID-19.

“As Mr. Manafort’s trial judge observed, prior to the Special Counsel investigation,” said the statement announcing the pardon, “Mr. Manafort had led an ‘otherwise blameless life’” that should not have been defined by his crimes.

“Mr. President, my family & I humbly thank you for the Presidential Pardon you bestowed on me,” Manafort wrote in a statement at the time. “Words cannot fully convey how grateful we are.”
