Russian billionaire Viktor Vekselberg, who was present at President Trump’s inauguration last year, was questioned by special counsel Robert Mueller’s team, a new report says.

Vekselberg’s electronic devices were searched and he was questioned after federal agents on Mueller’s team stopped him at a New York-area airport earlier this year, the New York Times reports.

Although there are no signs that Mueller believes Vekselberg has committed any wrongdoing, Vekselberg’s path has repeatedly crossed people in Trump’s circle.

For example, Vekselberg received a ticket to Trump's inauguration from his American cousin, according to the Times. Additionally, Vekselberg went to a dinner in Russia several years ago also attended by Russian President Vladimir Putin and former national security adviser Michael Flynn.

Flynn resigned last year from his White House post after it came to light he was dishonest about his communications with then-Russian Ambassador Sergey Kislyak and later pleaded guilty to lying to the FBI and committed to cooperating with Mueller's team.

Vekselberg was also one of 17 Russian officials who was hit with sanctions from the U.S. Treasury Department in April. These sanctions froze U.S. assets barred engagement in dealings with Americans or U.S entities.
