Earlier this week, Joe Biden’s campaign, struggling on the polling and fundraising fronts alike, finally dropped its reservations about relying on super PACs for support. The details of the new Unite the Country PAC, both in terms of reach and fundraising efforts, remain scant; a bland ad for the PAC featured little more than stock photos of children, Mars rovers, and former President Barack Obama. However, we know at least one name tapped with helping steer prospective millions toward pro-Biden efforts: Larry Rasky.

Listed on federal filings as the PAC’s new treasurer, Rasky is hardly a household name. Described by Politico as a “longtime Biden adviser,” Rasky was closely entwined with Biden’s previous unsuccessful runs for the White House—most recently as the communications director of Biden’s 2008 campaign. According to Bloomberg, Rasky has said that the new Super PAC would direct efforts at countering President Donald Trump’s ongoing, and entirely baseless, allegations that Biden was involved in corrupt practices in Ukraine. It’s understandable that the Biden camp would want to devote resources to pushing back on Trump’s risible claims: The president’s willingness to try to browbeat Kyiv into launching an investigation into a political rival is as impeachable as it is unprecedented.

But there’s another role Rasky recently maintained, and which Biden’s allies have downplayed. As documents filed with the Department of Justice’s Foreign Agents Registration Act (FARA) database show, Rasky and his PR firm, Rasky Partners, inked a deal with the kleptocratic dictatorship of Azerbaijan earlier this year, in which they said they would rake in nearly $100,000 to whitewash one of the most heinous post-Soviet regimes. As the filings illustrate, Rasky identified himself as providing “strategic communications, counsel, and services” to the Azeri embassy in the U.S.—with his underlings providing services ranging from “media monitoring” to, bizarrely, “outreach to influencers.”

One of Rasky’s spokespersons, Kirk Monroe, told The New Republic earlier this summer that Rasky’s company had been “retained to provide public relations support, but no lobbying services, which still requires a FARA filing. We took on the assignment because Azerbaijan is an important US ally trying to bring stability, peace and economic growth to the region.” Azerbaijan, it goes without saying, is not actually a U.S. ally, and dictatorships like Azerbaijan aren’t especially known for anything approaching peace or stability.

Rasky has said that he canceled his lucrative partnership with Azerbaijan’s dictatorship in August, although those documents aren’t yet available in the FARA database. Regardless, the fact remains that, for months, Rasky served as a foreign agent for a government that is perhaps the quintessential post-Soviet kleptocracy: the most brutal and bloodied regime in Europe, overseen by a family acting as the model for the kind of illiberalism and rapaciousness that other regimes in the region struggle to match.
