Mueller's Team Questioning Russian Oligarchs in Collusion Probe

Russian Federation probe special counsel Robert Mueller is reportedly looking into a meeting that President Donald Trump's son-in-law, Jared Kushner, attended with former United Arab Emirates adviser George Nader, who is cooperating in the investigation.

One oligarch, according to sources who spoke to CNN, had his electronic devices searched after his private jet landed at a NY airport.

Four sources said the sanctions would be imposed under the Countering America's Adversaries Through Sanctions Act, also known as CAATSA, which was passed by Republicans and Democrats seeking to punish Russian Federation for its 2014 annexation of Crimea from Ukraine, involvement in the Syrian civil war and meddling in the 2016 US presidential election. It was unclear if he had his devices scanned.

The Mueller team made an informal voluntary document and interview request to a third Russian oligarch who has not visited the United States, the report said.

It also suggests that Mueller's investigators might have obtained records or documents raising concerns about whether there was a flow of money from the Kremlin to the Trump campaign. One option being discussed with the president is to have him answer questions in writing and avoid a sit-down interview completely, sources said.

White House lawyer Ty Cobb also declined to comment, saying the president's legal team does not discuss conversations with the special counsel.

Why is Mueller's team stopping wealthy Russians at airports?

"We're not aware of this", Cobb told the Daily News Wednesday afternoon.

The Trump administration used CAATSA last month to slap sanctions against two-dozen Russian individuals and entities for their involvement in a two-year campaign of cyberattacks against the U.S.

Mueller's people also want to know if Russians may have used so-called "straw donors" - American citizens - as a way to pass off cash to the campaign or the inaugural fund.
