• Several of Donald Trump's top picks have recently been lobbyists.
• Susan Wiles, Trump's incoming chief of staff, maintained ties to a lobbying firm until this month.
• Sean Duffy, Trump's pick for Transportation secretary, has lobbied for a group of major airlines.

President-elect Donald Trump is set to rely on a trio of former lobbyists to help implement his agenda to shake up Washington.

Incoming White House chief of staff Susie Wiles, attorney general nominee Pam Bondi, and Transportation secretary nominee Sean Duffy have all been registered lobbyists. According to disclosure filings, Bondi and Wiles did lobbying work as recently as this year, with Duffy working as a lobbyist into 2023.

Their combined clients range from blue chip companies — including Amazon, GM, and Uber — to insurance giants like MetLife and Fidelity National Financial. Wiles and Bondi were also separately registered to lobby for foreign interests, which included one of Nigeria's largest political parties and the Qatarian embassy.

Wiles and Bondi have both once worked for Ballard Partners, once a regional firm in Florida that exploded in popularity due to its ties to Trump world. Earlier this summer, the firm opened an office in Riyadh, Saudi Arabia.

"Part of why you hired Ballard Partners over the last few years is knowing that if Trump is president, the people you are working with stand at having a pretty good chance at having influence in a Trump administration," Jeff Hauser, executive director of the Revolving Door Project, a public interest group, told Business Insider.

Brian Ballard, a major Republican fundraiser and founder of the firm, did not immediately respond to Business Insider's request for comment.

Wiles continued to have K-Street ties as she helped run Trump's campaign.

Wiles, according to The New York Times, did not cut ties to her most recent firm until Trump announced his intention to have her lead his second White House.

Her past work included an effort to get the Trump administration to approve a cooper and gold mine in a sensitive area of Alaska. Sen. Lisa Murkowski, an Alaska Republican, widely viewed as a key vote in the narrowly divided US Senate, and other top state officials have long opposed the Pebble Partnership. The EPA, under Obama, Trump, and Biden's administrations, have repeatedly opposed efforts to mine in the bay, home to one of the world's largest salmon fisheries.

Duffy, who if confirmed would oversee the Federal Aviation Administration, lobbied in 2020 for an airline group that includes American, Delta, and United among its members.

Starting not long after he left Congress in 2019, Duffy lobbied for Polaris, a US auto manufacturer known its off-road and recreational vehicles. Former lawmakers are only restricted from lobbying Congress for a year, though they can immediately lobby the rest of the federal government. According to his disclosures, Duffy's work at times included advising the company on how to navigate EV incentives and tariffs.

ProPublica previously reported that Duffy lobbied White House trade adviser Peter Navarro as Polaris sought to win exemptions to tariffs on the parts it was importing. ProPublica found that Polaris' efforts, including use of Duffy, ultimately led the company to get most of what it wanted.

Bondi's work for Amazon was related to trade and tariff policy, according to disclosures. She also lobbied for General Motors, Uber, Fidelity National, Carnival North America, and even Major League Baseball.

Trump didn't start the revolving door, but the swamp could get larger.

Wiles, Bondi, and Duffy's respective work all fits within the larger revolving door narrative that dominates Washington, even as Trump portrays himself as ready to shake up the status quo.

Ron Klain, President Biden's first chief of staff and longtime adviser, was a lobbyist for Fannie Mae in the early 2000s. Steve Ricchetti, another longtime Biden fixture, spent so much time lobbying that top Obama administration officials tried to prevent then-Vice President Biden from hiring him after the 2008 election. His brother Jeff Ricchetti, who remains a registered lobbyist, saw his business boom after Biden won the 2020 election.

President Barack Obama initially received high praise for his limits on hiring lobbyists who had recently lobbied the federal agency they sought to join, though he granted some limited waivers including to a former top lobbyist to Raytheon. Ultimately, Obama was unable to stop the revolving door, as Politico reported in 2015.

Hauser said what stands out about the Trump team so far is their unorthodox approach to the transition, including refusing to sign formal agreements with the current administration which would include ethics guidelines.

While Trump, like Obama and Biden, issued an ethics-related executive order after taking office in 2017, Hauser isn't convinced it will happen again.

"Given the aversion of his transition to the ethics process of the transition, I think it's an open question whether or not he is going to make his appointees sign additional ethics pledges in office this time," Hauser said.
