Tester says his Palantir job isn’t lobbying. His influence restriction runs through Jan. 2.

Palantir has hired former Democratic Sen. Jon Tester as an adviser while an official Senate record says his two-year post-employment restriction remains in force through Jan. 2, 2027. Tester told NPR his agreement is “advisory in nature” and “not lobbying.” No public evidence reviewed by Public Rot shows he has violated the restriction.

The distinction matters. Federal law does not bar a former senator from taking a private job or giving behind-the-scenes advice. During the two-year period, it bars intent-to-influence communications or appearances, on behalf of another person, before members and employees of Congress when official action is sought. Senate Ethics says the rule is enforced by the Justice Department.

NPR reported the hire on Nov. 9 as Palantir prepares for scrutiny from the incoming Democratic Congress. Sen. Ron Wyden’s office told NPR that he intends to renew questions about the company when he chairs the Finance Committee and that compulsory process could be used. Tester said Palantir has “a good story to tell” and people should be receptive to it.

That sequence creates a revolving-door question even without evidence of a legal breach. Tester built part of his record as a critic of broad surveillance, including opposition to reauthorizing the PATRIOT Act. NPR reported that former Palantir employees criticized a $30 million Immigration and Customs Enforcement tool that gave the agency near-real-time visibility into migrant movement.

Tester’s defense is substantive. He told NPR that Palantir is different from the surveillance programs he criticized and said he will advise the company on improving delivery of government services. Palantir says it does not build a single government-wide master database, that its deployments are agency-specific, that customers control their own data, and that legal and technical privacy protections apply.

Lawmakers’ allegations are not findings. In a 2025 letter, Wyden and Rep. Alexandria Ocasio-Cortez questioned reports that Palantir was helping the IRS build a “mega-database” and asked whether tax and privacy laws were being followed. Palantir’s published response called the allegations false and said no such whole-government project existed.

Nor does the label “not lobbying” settle the public-interest issue. A lobbying registration has its own statutory thresholds and definitions; the Senate cooling-off rule separately turns on whether an intent-to-influence communication is made. Public Rot found no evidence that Tester has made such a contact or that a lobbying registration is currently required.

The immediate accountability test is disclosure. Tester and Palantir should publish his compensation, role scope and written safeguards against covered congressional contacts through Jan. 2. They should also say whether congressional advocacy is expected after the restriction expires. Those facts would distinguish ordinary advice from the sale of political access.
