Welcome to our deep dive today. We're looking at a ProPublica investigation published in September 2026 that details a sweeping FBI public corruption probe involving Senator Susan Collins and a defense contractor called Navatek. It's a story about alleged pay-to-play, shell companies, and ultimately, an investigation that was shut down. Joining me is an expert on campaign finance and federal corruption cases. Thanks for being here.
Guest
Thanks for having me. This is a fascinating and frankly troubling case. The ProPublica report pulls back the curtain on how influence might actually be bought in Washington, and then how the machinery of accountability can grind to a halt.
Host
Let's start with the basics. Who are the key players here? We have Senator Collins, a long-time Maine Republican, and Navatek, which later became Martin Defense Group. And then there's Martin Kao, the former CEO.
Guest
Right. Martin Kao is central. He's currently serving an 87-month prison sentence for fraud and campaign finance crimes. But before his sentencing, he cooperated with the FBI and provided a detailed account of what he says was a systematic scheme to trade campaign cash for federal contracts. And the FBI, according to ProPublica, independently corroborated much of his story through internal emails and corporate records.
Host
So what exactly was this scheme? The article mentions something called "the method." Can you explain that?
Guest
Sure. Under Kao's leadership, Navatek developed a strategy they literally called "the method." The idea was to identify powerful members of the House and Senate appropriations committees—the people who control the purse strings—then make significant campaign donations to them, and then work with their staff to insert specific language into the defense budget that only Navatek could fulfill. It's a classic pay-to-play model, but with a corporate twist.
Host
That sounds like legalized bribery, if true. But how did they get around the fact that government contractors are barred from making political contributions?
Guest
That's where it gets really interesting. In late 2019, Kao met with Scott Reed, who ran the super PAC supporting Collins, called 1820 PAC. According to Kao's confession to the FBI, Reed asked for a $500,000 donation. But because Navatek was a government contractor, it couldn't legally donate. So Kao proposed using a shell company to hide the source.
Host
And that shell company was called the "Society of Young Women Scientist and Engineers"? That seems like an odd choice.
Guest
It does, doesn't it? But that's exactly what they used. Navatek funneled $150,000 to the 1820 PAC through that shell company. ProPublica obtained emails where Kao explicitly told Reed that the shell company was a way to "conceal the identity" of the donor. And Reed's response? "Very smart." That's a pretty damning exchange if you're trying to argue there was no intent to evade the law.
Host
So the money went through, and then what? The article mentions a private meeting where Collins allegedly said something like "You've seen me deliver."
Guest
Yes. Kao alleged that in a private meeting with Collins and her staff, the senator told him, "You've seen me deliver," referring to the federal funding she had secured for his company. And shortly after the shell company donation was made, Collins' campaign staff reportedly told Kao that the senator "would like to call Martin to thank him." Now, Collins' office denies any bribery or pay-to-play, calling Kao's claims "outlandish." But the timing is certainly suspicious.
Host
Let me push back a bit here. Martin Kao is a convicted felon who was trying to avoid a lengthy prison sentence. How much weight should we give to his testimony?
Guest
That's a fair point, and it's one that Collins' team has emphasized. But ProPublica's reporting indicates that the FBI didn't just take Kao's word for it. They had internal emails, corporate records, and other evidence that corroborated key parts of his account. For example, the emails about the shell company and Reed's "Very smart" response are not just Kao's memory; they're documented. So while Kao's credibility is certainly open to challenge, the paper trail is harder to dismiss.
Host
And what about the actual contracts? The article suggests that Navatek's research was often useless—like a 3D-printed boat that the military didn't want.
Guest
Right. ProPublica found that despite receiving tens of millions in federal funding steered by Collins, Navatek's research often resulted in products the military did not want or use. Former employees described the work as being designed primarily to generate "PowerPoint slides and a white paper" to justify the funding. So it wasn't just about getting money; it was about creating the appearance of legitimate work while the real goal was the funding itself.
Host
That's a devastating critique. So the FBI was investigating all of this. What happened to the case?
Guest
The investigation took a significant turn in late 2024. After Donald Trump returned to office, the investigation—which had expanded into a broader probe of several powerful lawmakers—was effectively shut down. ProPublica reports that the specialized FBI and DOJ teams handling the case were "eviscerated" as part of a purge of agents who had previously investigated Trump. So the people who were building the case were removed, and the case essentially died.
Host
That's a remarkable claim. Can you elaborate on this purge? Why would an investigation into a Republican senator be affected by a purge of agents who investigated Trump?
Guest
Well, the article suggests that the purge was broad and targeted anyone involved in investigations that touched Trump or his allies. Collins, while not directly a Trump ally in the same way as some others, was still a Republican senator, and the investigation into her was part of a larger public corruption probe that may have implicated other powerful figures. By removing the agents and prosecutors who were driving these cases, the new administration effectively shut down a potential window into how Washington works.
Host
And Martin Kao's cooperation? The article mentions a 50-page "road map" of corruption.
Guest
Yes, before his sentencing, Kao provided the FBI with a 50-page document detailing interactions with over a dozen members of Congress. That's a significant amount of information. It suggests that the alleged pay-to-play wasn't limited to Collins; it may have been a systemic practice. But with the investigation shut down, that road map may never be fully explored.
Host
Senator Collins' office has vigorously denied any wrongdoing. What exactly is their defense?
Guest
Her deputy chief of staff, Annie Clark, stated that the campaign fully cooperated with the FBI and that the matter was resolved in 2021 when illegal contributions were returned. They label Kao's claims as "outlandish." So their position is that they did nothing wrong, they cooperated, and the only issue was the illegal contribution from the shell company, which they returned once they learned about it.
Host
But if the matter was resolved in 2021, why was the FBI still investigating in 2024? That seems contradictory.
Guest
That's a key question. The fact that the investigation continued for years after 2021 suggests that the FBI did not consider the matter fully resolved. The return of the illegal contribution might have addressed one narrow issue, but the broader allegations of pay-to-play and the "method" strategy likely remained under scrutiny. The shutdown in late 2024 effectively ended that scrutiny before any charges could be brought.
Host
So what's the broader significance of this story? Why should people care?
Guest
The significance is twofold. First, it shows how campaign finance laws can be circumvented through shell companies and how the appropriations process can be manipulated for private gain. Second, and perhaps more importantly, it shows how political pressure can shut down investigations into powerful people. As one former official told ProPublica, the closure of the investigation "shut a potential window into how Washington works." That's a chilling statement because it implies that we may never know the full extent of the corruption.
Host
That's a sobering thought. And it leaves us with a lot of unanswered questions. Do you think there's any chance the investigation could be revived?
Guest
It's hard to say. The current administration has shown little interest in pursuing public corruption cases that might implicate its allies. And with the specialized teams disbanded, the institutional knowledge and momentum are gone. It would take a significant change in priorities or new evidence to restart this. For now, it seems like the case is effectively dead.
Host
Well, thank you for walking us through this complex and troubling story. It's a reminder that the systems we rely on for accountability can be fragile. We appreciate your insights.
Guest
Thank you. It's an important story, and I hope it sparks more discussion about how we can strengthen those systems.
Host
That's all for today. Thanks for listening, and we'll be back with more deep dives soon. Goodbye.
