Mike Bloomberg, whose pitch to Democratic voters is that he remains untouched by special interests, has invited a team of special-influence peddlers to manage his campaign. The technology and media executive, and former New York City mayor has made ethics a central part of his message, claiming that his decision to rely only on his own $53 billion fortune to finance his campaign makes him uniquely incorruptible. But in his bid for the presidency, Bloomberg has retained a circle of staff and advisers who have a long history of working as consultants and lobbyists for corporate interests.

Bloomberg spokesperson Stu Loeser, before joining the campaign, was retained by Purdue Pharma, makers of OxyContin, to combat widespread criticism that the company had fueled the opioid addiction crisis. Mitch Stewart, the campaign’s senior adviser on campaign strategy, runs a firm called 270 Strategies, which has provided lobbying and consulting work for a number of corporate clients, including the Coalition for Investor Choice, a group seeking carve-outs from financial regulations passed under the Obama administration. Stewart’s firm previously courted controversy when it created an anonymously funded group to lobby Democrats in support of the Trans-Pacific Partnership. Campaign manager Kevin Sheekey previously helped lead lobbying strategies for Bloomberg LP, the business founded by the candidate. Sheekey, for instance, developed a broad coalition effort in Washington, D.C., to influence regulators overseeing the NBC-Comcast merger to ensure favorable treatment for Bloomberg’s financial news television program. Bradley Tusk, an adviser to Bloomberg’s campaign and his former mayoral campaign manager, previously worked as a lobbyist for Uber, helping the ride-hailing company beat back New York limits on for-hire vehicles. He later worked to win passage of laws in seven states designed to exempt gig-economy workers from labor rights such as minimum wage and the right to organize a union. Tusk Strategies, his consulting firm, is currently registered to represent the Police Benevolent Association of the City of New York, the powerful police union; internet payday loan provider MoneyLion; and Bird Rides, among other clients. Many of the recently hired staff to Bloomberg’s presidential campaign have previously worked as business lobbyists or government affairs officials, including political staff tapped to run local campaign operations in Georgia, Arizona, Maine, Pennsylvania, Colorado, and Mississippi. Reached for comment, the campaign pointed to campaign finance reforms supported by the former mayor and noted that Tusk is not directly employed by the campaign.
