What to know about the pay-to-play allegations against Susan Collins

Key Points:

• ProPublica revealed an FBI investigation from 2020 to 2025 into alleged bribery involving Senator Susan Collins’ campaign donors and millions in federal defense contracts linked to contractor Martin Kao, who claimed Collins steered contracts in exchange for campaign donations.
• Collins' office denies wrongdoing, emphasizing that the campaign was never targeted by the FBI, and highlighting Kao’s criminal convictions and history of lying, while ProPublica independently corroborated many of Kao’s claims through internal communications and emails.
• The investigation reportedly stalled after the 2024 election when the Trump administration purged corruption investigators and dropped cases, including those involving Collins and other lawmakers, despite FBI findings suggesting sufficient evidence for further probes.
• Navatek, Kao’s company, employed a strategy of partnering with universities and targeting states with influential lawmakers like Collins to secure federal contracts, though Kao admitted the company’s products had little real military value.
• Democrats have seized on the report to criticize Collins for alleged corruption and favoritism toward wealthy donors, with her 2024 opponent Troy Jackson calling the allegations “corruption of the highest order,” while Collins’ campaign calls the ProPublica story “categorically false.”
