The Guardian last night published the leaked news that Trump's nominee for Secretary of State, Exxon-Mobile CEO Rex Tillerson, has since 1998 been a director of a U.S.-Russian oil firm that is based in the Bahamas, a prime location for tax haven corporations.
I don't yet understand the reason this has been a secret. Documents from the company have previously listed him simply as R.W. Tillerson, along with other directors from the U.S. and from Russia. Apparently there is nothing illegal about it, but why would it have been previously unreported? The corporation is involved in off-shore drilling in the Aral Sea.
Tillerson protested the U.S.government's sanctions against Russia beginning in 2014; and it will certainly raise further questions about the appropriateness of his Sec. of State appointment. Marco Rubio, who sits on the Senate Judiciary Committee which will hold Tillerson's confirmation hearings, has already expressed "serious concerns" about confirming Tillerson because of his ties to Russia.
