FBI Drops Collins Bribery Probe as Trump Purges Corruption Units

Key points

• FBI investigated a pay-for-play scheme involving Sen. Susan Collins and Navatek, a defense contractor, in 2024.
• Martin Kao, Navatek’s CEO, confessed to bribing lawmakers with nearly $900,000 in donations to secure over $40 million in annual contracts.
• The investigation was closed in 2025 after the Trump administration purged the FBI’s public corruption unit and fired key agents.
• Collins’ office denies wrongdoing, stating the campaign disgorged illegal contributions and fully cooperated with the FBI.
• Critics, including Democratic challenger Troy Jackson, label the case 'corruption of the highest order' and accuse the administration of cover-up.

Background

This story follows earlier coverage of the FBI’s stalled pay-to-play probe into Collins, which was linked to Navatek’s CEO Martin Kao. Previous reports noted that Kao pleaded guilty in 2022 to illegal campaign contributions, while Collins’ office maintained that the matter was resolved. The current development highlights the impact of the Trump administration’s purge of the FBI’s anti-corruption units on ongoing investigations.

How outlets are covering it

ProPublica and Rolling Stone emphasize the political interference, arguing that the Trump administration’s dismantling of the FBI’s public corruption unit killed the investigation. They highlight Kao’s detailed confessions and emails suggesting a quid-pro-quo arrangement. The New York Times reports that the FBI closed the case in 2025 due to doubts about Kao’s credibility, while the FBI spokesperson Ben Williamson stated the agency found nothing implicating Collins. Esquire frames the story as a sketchy example of the DOJ’s abandonment of public corruption cases, criticizing the administration’s actions. Collins’ office denies any impropriety, calling Kao’s claims 'outlandish' and asserting full cooperation with the FBI.

Why it matters

The case underscores the potential impact of political interference on federal investigations and the integrity of the justice system. It raises questions about the accountability of elected officials and the effectiveness of anti-corruption efforts in the current administration.

What to watch

The investigation is dead, and the government is no longer engaging with Kao. Collins faces a critical Senate race, with her opponent Troy Jackson using the case to challenge her integrity. The FBI has stated it found no wrongdoing, but the closure of the case has sparked debate about the independence of federal law enforcement.
