A Bulgarian businessman and ex-politician who hopes to roll back corruption-related sanctions he was slapped with last year has hired Morgan, Lewis & Bockius as his attorneys in the case.

“All of Plaintiffs’ property and interests in property within the United States or within the possession or control of U.S. persons, wherever located, are blocked, meaning they cannot be transferred, paid, exported, withdrawn or otherwise dealt in by U.S. persons,” wrote Delyan Slavchev Peevski, who was among a group of Bulgarian’s added to the Specially Designated Nationals and Blocked Persons List last summer after the State Department linked them to corruption in the western European nation.
