A former lobbyist for the pesticide industry now leads the deregulatory team at the USDA. Visitor logs show old ties remain strong.

At a private meeting in September, congressional aides asked Rebeckah Adcock, a top official at the Department of Agriculture, to reveal the identities of the people serving on the deregulation team she leads at the agency.

Teams like Adcock’s, created under an executive order by President Trump, had been taking heat from Democratic lawmakers over their secrecy. What little was publicly known suggested that some of the groups’ members had deep ties to the industries being regulated.

Adcock, a former pesticide industry executive, brushed off the request, according to House aides familiar with the exchange, who asked for anonymity because they were not authorized to comment publicly. Making the names public, they recalled her saying, would trigger a deluge of lobbyists.

In fact, interviews and visitor logs at the Agriculture Department showed that Adcock had already been meeting with lobbyists, including those from her former employer, the pesticide industry’s main trade group, CropLife America, and its members. CropLife pushes the agenda of pesticide makers in Washington, including easing rules related to safety standards and clean water.

Adcock, who left the trade group in April, maintained contact with her former industry allies despite a signed ethics agreement promising to avoid for one year issues involving CropLife as well as matters that she had lobbied about in the two years before joining the government.

In one meeting, Adcock discussed issues banned by the ethics agreement with an executive who had been her lobbying partner weeks earlier at CropLife, according to the accounts of participants and the visitor logs, obtained through a public records request by The New York Times and ProPublica.

Tim Murtaugh, a spokesman for the USDA who also spoke on behalf of Adcock, said she had not violated her ethics agreement by meeting with her former industry allies. He also denied that Adcock had discussed issues related to her previous lobbying at the meeting, or that she had suggested that her deregulation team would be swamped by lobbyists if names of its members were released.
