Buzzfeed is being sued by a Russian tech firm after it published the company owner’s name in a report last month on an unverified dossier concerning President Trump, according to a report Friday.

XBT Holdings, a Cyprus-based company owned by Russian tech magnate Aleksej Gubarev, has filed defamation lawsuits against Buzzfeed, its editor-in-chief, Ben Smith, and former British intelligence agent Christopher Steele, McClathy reported Friday.
