Sometimes in journalism, like in child-rearing, it takes a village.

In the wake of the Parkland school shooting, an investigative news outlet called the Florida Bulldog reported on Kalashnikov USA, a shady gunmaker with ties to Russia. The company, it seemed, had found a way to produce Kalashnikov-branded AK-47s in the U.S. without running afoul of U.S. sanctions. And in 2015 it had inked a deal with Gov. Rick Scott’s administration to open a factory a few miles from Parkland in exchange for tax breaks. (The tax deal fell through when the company failed to create enough jobs, but the gunmaker did move to Broward County.)

At TPM, we’ve been reporting on the NRA’s Russian links, so the story piqued our interest. We dug into Kalashnikov USA’s relationship with Kalashnikov Concern, the Russian company that makes Kalashnikovs and is subject to sanctions, raising questions about just how separate the two firms really were. It also seemed weird that Kalashnikov USA had been promising for years to start making the AK-47s, but there was very little evidence that they had succeeded. And when we asked a Kalashnikov USA official about the company’s activities, he hung up on us.

Then last month Bloomberg picked up the torch, reporting on ties between a top Kalashnikov USA exec and the CEO of Kalashnikov Concern, and exposing a system of shell companies that may link the two firms.

Finally, on Thursday, Rep. Ted Deutch (D-FL) called on the Treasury Department to probe whether either of the companies had violated sanctions. Citing news reports, Deutch accused Kalashnikov USA of using a “web of shell companies to hide its relationship” to Kalashnikov Concern. “This case deserves a full investigation to determine whether federal laws were broken to protect Kalashnikov’s profits,” he said.

It’s nice to see some validation for our instinct that there was something fishy going on here. Let’s hope Deutch and co. can get some answers.
