Trent Lott's company made $450,000 from a Kremlin -controlled bank that was the target of US sanctions.

Oh, and Haley Barbour reaped some cash also. 

Bloomberg Reports:

• While Russia may be angry about international sanctions over the Ukraine conflict, Beltway lawyers are mopping up and big names in lobbying are piling in.
  Consider that last year, the Washington, D.C., lobbying firm of former Senate Majority Leader Trent Lott raked in $300,000 from Kremlin-controlled OAO Gazprombank, which was a target of sanctions. The Gazprombank billings for Lott’s firm are about double what Lott made in annual salary during any of his 18 years in the Senate.
  Other high-profile ex-senators like John Breaux of Louisiana and Don Nickles of Oklahoma are also getting in on the Russian action, as is Haley Barbour, the former governor of Mississippi.
  What’s driving this is no mystery. While the West expresses displeasure at President Vladimir Putin’s deadly Ukraine adventuring and the human toll it is taking, other things are at stake -- notably billions of dollars of investments on both sides of the Atlantic in Russia’s energy and finance sectors.
