Mueller questioned Russian oligarch close to Putin about payments to Michael Cohen: report

Special counsel Robert Mueller has questioned Russia oligarch Viktor Vekselberg about a payment his company allegedly made to Donald Trump's personal attorney Michael Cohen, CNN reports.

According to a "source familiar with the matter," the payment totaled hundreds of thousands of dollars and was made via a U.S. affiliate of Vekselberg's Russian conglomerate Renova Group.

CNN reports the payments were made after the election.

In May, it was reported that Vekselberg was questioned by Mueller's team "as he exited his private plane on the tarmac in a New York City airport."

Vekselberg owns part of the Bank of Cyprus, the financial institution that last year turned over former Donald Trump campaign chairman Paul Manafort's records to Mueller, according to Bloomberg.

On Tuesday, Michael Avenatti—the lawyer representing adult film star Stormy Daniels—released an "executive summary" about the payments allegedly made to Cohen.
