Did Susan Collins Trade Federal Contract Support for Navatek Campaign Donations?

Martin Kao alleged that Susan Collins knowingly linked Navatek campaign support to federal-contract assistance. Collins's office and other participants deny a quid pro quo, while official records establish separate illegal contributions by Navatek-linked actors.

Overview

Navatek and its executives pursued federal research funding while donating to Susan Collins's campaign and to 1820 PAC, an independent committee supporting her 2020 reelection. Federal records later established that Navatek money had been routed through a shell company and reimbursed contributors in violation of campaign-finance law. Kao subsequently told FBI agents that donations were part of a broader pay-to-play method and alleged that Collins understood the exchange. ProPublica reported emails and internal records consistent with portions of his account. Collins's deputy chief of staff called the allegations categorically false and outlandish; an FBI spokesperson said an earlier investigation found nothing implicating Collins or her campaign. Scott Reed, Glen Mandigo and Andy Winer also denied communications, advice, knowledge or participation that would establish a contribution-for-official-action agreement. Kao was seeking sentencing consideration when he cooperated, and no one working for Collins was charged. The dispute is whether Collins knowingly participated in an exchange, not whether Navatek-linked illegal contributions occurred.

      Source release

      In the second story of a series on the FBI's Navatek inquiry, ProPublica reports that Kao told agents his business model consisted of bribing public officials in exchange for government contracts and that Navatek primarily targeted lawmakers from smaller states on appropriations committees, such as Collins. The story centers on Kao's allegations about the late Sen. Lindsey Graham and Reps. James Clyburn and Joe Wilson. Graham's and Clyburn's offices reject the allegations, Wilson's office says he follows federal campaign donation rules, and Collins has denied wrongdoing. ProPublica reports that the investigation went dark after the agents on it were fired or pushed out of the FBI; an FBI spokesperson calls Kao's claims "half baked" and "misleading".

  1. Susan CollinsU.S. senator from Maine and Republican candidate for reelectionDirectly involved

    Before this statement

    A reporter asks Collins about an ethics complaint filed the previous week by a Maine attorney. Collins says the allegations were recycled from 2020 and had been rejected by the Department of Justice, the FBI and the Federal Election Commission.

    "The allegations are completely false ... We have a picture of his meeting with me and with other people in my office that is many months before he ever made a single contribution ... He spun this story up again in the hopes that the judge would be lenient, or the prosecutor would be."
    Denied

    Case context: Did Susan Collins Trade Federal Contract Support for Navatek Campaign Donations?

    Full statement and sources

    Asked about the Senate ethics complaint, Collins says the allegations are completely false and were rejected by the Justice Department, the FBI and the Federal Election Commission. She says a photo shows Kao met her months before he made any contribution and that he revived the story hoping for leniency.

    After the statement

    Pressed on why she would not welcome an ethics inquiry to clear her name, Collins says it is not up to her, attributes the complaint to partisan Democrats and a lawyer who lost her primary, and says she was never interviewed because there was no evidence.

    Why this label?

    The case asks whether Collins traded support for Navatek's federal contracts for campaign donations. Collins rejects the allegation outright and disputes the account's timeline, so we used the denies label.

    This label describes the statement's response within the context above.

  2. Susan CollinsRepublican U.S. senator from Maine, through campaign spokesperson Blake KernenDirectly involved

    Before this statement

    The Press Herald asked whether Collins herself would comment on whether she called Kao. Campaign spokesperson Blake Kernen said it "does not appear in any of our records that this call was made."

    "Neither Susan Collins nor anyone who worked for her believes that she made a call"
    Denied

    Case context: Did Susan Collins Trade Federal Contract Support for Navatek Campaign Donations?

    Full statement and sources

    Asked by the Portland Press Herald whether Susan Collins called Navatek CEO Martin Kao to thank him for a 2019 super PAC donation, her campaign spokesperson said there is no record of the call and that neither Collins nor anyone who worked for her believes she made it.

    After the statement

    The campaign and its manager, Steve Abbott, had said the week before that they did "not believe" the senator ever called Kao.

    Portland Press Herald: The laws tied to the Collins-Navatek allegations are 'crystal clear.' Enforcing them is another matter.Section "Did Collins actually call Kao to thank him?"; statements from campaign spokesperson Blake Kernen.

    Why this label?

    The case asks whether Collins traded federal contract support for Navatek campaign donations. ProPublica reported that a Reed aide sought Kao's number because Collins "would like to call Martin to thank him." The campaign denies the call took place, so we labeled it Denies.

    This label describes the statement's response within the context above.

  3. Susan CollinsU.S. Senator for Maine, the senator whose conduct is at issueDirectly involved

    Before this statement

    Hours after ProPublica published its investigation into whether Collins traded federal contract support for Navatek campaign donations, and after her deputy chief of staff Annie Clark issued a written denial, Collins spoke directly to reporters just off the Senate floor about the allegations.

    "In 2021, the Biden Justice Department found there was no wrongdoing by anyone on my campaign staff, my office or me. This is absolutely outrageous. It's clearly a political hit job."
    Denied

    Case context: Did Susan Collins Trade Federal Contract Support for Navatek Campaign Donations?

    Full statement and sources

    Collins personally denies the pay-to-play allegations, citing a 2021 Biden Justice Department finding of no wrongdoing by her, her office, or her campaign, and calls the ProPublica report a political hit job driven by Democratic tactics; she also calls Kao a liar with multiple federal convictions.

    After the statement

    Collins also blamed the timing and framing of the story on Senate Minority Leader Chuck Schumer and Democratic tactics, and separately called Martin Kao a liar who has been twice convicted in separate federal court cases, including for money laundering.

    Susan Collins slams ‘political hit job’ on Justice Department probeparagraphs 1-8, quoting Collins speaking to reporters off the Senate floor

    Why this label?

    On whether she traded federal contract support for Navatek campaign donations, Collins says the Biden Justice Department already investigated and found no wrongdoing by her, her staff, or her campaign. That is a direct denial that the alleged conduct occurred, not merely a dispute over how the story is framed.

    This label describes the statement's response within the context above.
