Posobiec repeatedly linked on Twitter to the obscure website “SouthFront,” which the U.S. Department of the Treasury named on April 15 in a statement explaining its enactment of sanctions on the Russian government, Hatewatch found. SouthFront, in turn, made posts promoting Posobiec. Southfront also cited Posobiec’s tweets in their posts, as they did in February when announcing that Senate Republicans acquitted President Trump on charges related to his role in the Jan. 6 insurrection. Posobiec has used Twitter to promote Russian intelligence-backed propaganda before, as when he served as a central figure in spreading a hack of Emmanuel Macron’s emails in May 2017, as Hatewatch has previously reported.
