A new investigation by ProPublica is drawing attention to allegations involving Sen. Susan Collins, R-Maine, defense contractor Navatek and political donations, including a reported $150,000 contribution to a Collins-affiliated super PAC.
According to ProPublica, the FBI examined allegations that Martin Kao, the former CEO of Navatek, may have sought to exchange political contributions for government contracts. Kao later pleaded guilty to federal campaign finance offenses and other crimes.
The allegations involving Collins remain disputed. No one working for Collins was charged in connection with the reported allegations. Collins’ office has denied wrongdoing, while an FBI spokesperson said an earlier investigation into Collins ultimately found nothing implicating the senator or her campaign.

What ProPublica Reported
ProPublica reported that federal investigators examined Kao’s account of his dealings with lawmakers after he was indicted for campaign finance violations.
According to the investigation, Kao told FBI agents that political donations were part of a broader effort to obtain government funding and contracts for Navatek. ProPublica said investigators also reviewed corporate records, emails and other evidence while examining his claims.
The reporting focused particularly on Collins because of her position on the Senate Appropriations Committee and her office’s involvement in federal funding connected to Navatek.
ProPublica reported that Collins’ office helped direct millions of dollars toward Navatek-related projects while people associated with her political operation were seeking contributions from Kao and people in his network. The investigation also described a $150,000 contribution that Kao allegedly routed through a shell company to a Collins-affiliated super PAC.
The exact legal significance of those events remains disputed. ProPublica itself noted that proving a criminal bribery case involving an elected official requires evidence of a specific quid pro quo, and Kao had credibility issues because he was a convicted defendant seeking a reduced sentence.
What Martin Kao Told Investigators
According to ProPublica, Kao described a broader system in which Navatek sought government funding while making political contributions.
The report says investigators did not rely solely on Kao’s statements. ProPublica reported that the FBI reviewed extensive records and found evidence that supported portions of his account, including emails and financial records involving Navatek’s political activity.
One of the issues examined was a $150,000 payment to the Collins super PAC. ProPublica reported that the contribution came through an entity that obscured Navatek’s involvement.
The investigation also reported that emails and other records showed interactions between Navatek representatives, lobbyists and people connected to Collins’ political operation.
However, evidence that political donations and government funding occurred around the same period does not by itself establish that Collins personally agreed to a criminal exchange. The allegations remain contested.
FBI Investigation And Collins’ Response
ProPublica reported that FBI agents interviewed Kao during 2023 and 2024 and considered whether his information could support a broader public-corruption investigation.
An FBI spokesperson, Ben Williamson, told ProPublica that the bureau had investigated Collins years earlier and “ultimately found nothing implicating Senator Collins or Senator Collins’ campaign.” The FBI did not answer ProPublica’s questions about the newer investigation reportedly developed from Kao’s cooperation.
Collins’ office has strongly rejected the allegations.
Her deputy chief of staff, Annie Clark, disputed the characterization of the senator’s relationship with Navatek and denied that Collins or her campaign engaged in a pay-to-play arrangement. Scott Reed, who leads the Collins-affiliated super PAC, also denied communicating with Collins or her staff about Kao or Navatek, according to ProPublica.
The senator’s office also said campaign personnel cooperated with investigators and that the campaign was never the target of the investigation.
Why The Navatek Allegations Matter
The controversy centers on the relationship between political fundraising and federal spending.
Government contractors are subject to restrictions on political contributions, and federal bribery law requires more than simply showing that a politician received campaign support while a company benefited from government action.
That distinction is important in this case. ProPublica reported that investigators found evidence supporting parts of Kao’s account, but the reporting also noted the challenges prosecutors would face in establishing a criminal quid pro quo involving elected officials.
Kao himself pleaded guilty to federal offenses and later received a prison sentence. His statements to investigators therefore come from a convicted defendant who had an incentive to cooperate with prosecutors, a limitation that investigators and journalists had to consider.
The 2026 Maine Senate Race
The ProPublica investigation comes as Collins seeks another term in the U.S. Senate.
Democrat Troy Jackson is challenging Collins in the 2026 Maine Senate race. Jackson has criticized the allegations and called for greater scrutiny of the senator’s dealings involving federal contracts.
The Collins campaign has rejected the accusations.
The allegations are therefore an issue in an ongoing election campaign, but the available reporting does not establish that Collins committed a crime. The FBI has said its earlier investigation found nothing implicating Collins or her campaign, while ProPublica’s newer reporting describes a separate investigative effort that was being considered after Kao’s cooperation with federal investigators.
What Happens Next?
The central questions are whether federal investigators will pursue additional evidence, whether any new investigation will continue, and whether additional records or witnesses will clarify the relationship between Navatek’s political contributions and federal funding.
For now, the public record contains competing accounts: ProPublica has reported evidence and investigative activity involving Kao’s allegations, while Collins’ office denies wrongdoing and the FBI has said an earlier investigation found nothing implicating the senator or her campaign.
As the 2026 Maine Senate campaign continues, additional reporting or official action could provide more information about the allegations and the federal government’s handling of the matter.
