Nothing, I don't think. There are bundlers (who knows who they recruit to get donations) and there are people who host fundraising events.
Here are some bundlers working for Pete:
Steve Elmendorf—partner and co-founder of lobbying firm Subject Matter
Elmendorf lobbied for multiple members of the Partnership for America’s Health Care Future, a health care industry-funded nonprofit founded to defeat Medicare for All and Medicare public-option plans. As of the third quarter of this year, Elmendorf was also registered to lobby for the Federation of American Hospitals, oil company BP America, Wall Street giant Goldman Sachs, Verizon, Facebook, and dozens more corporate clients.
Bradley Tusk—NYC lobbyist and political consultant for Uber and other startups
Tusk, dubbed “Silicon Valley’s favorite fixer,” hosted an Oct. 21 campaign event for Buttigieg in Manhattan. Previously, Tusk was a top aide to former Illinois Gov. Rod Blagojevich, who was convicted of federal corruption, and was campaign manager for Mike Bloomberg’s successful third term for New York City Mayor, made possible only after a 29-22 Council vote in October 2008 to change the city’s term-limit laws. Consulting for Uber, an August 2018 Wall Street Journal profile credited Tusk with delaying for years sought-after regulatory caps on the company’s growth by New York City government. Tusk is currently a registered lobbyist for the Patrolmen’s Benevolent Association of the City of New York (PBA), the largest labor union representing police officers in the city.
Here are some people who have hosted fundraisers for Pete:
David Fares— 21st Century Fox senior vice president of government relations
As vice president of government relations at 21st Century Fox, Fares oversees millions of dollars in lobbying expenditures each year aimed at influencing the federal government and states on issues like intellectual property enforcement, taxes, data privacy, and media ownership rules.
Thaddeus Burns—head of public affairs at Merck
Burns hosted a campaign event in Geneva on Oct. 24 at the home of former Ambassador to Finland Charles Adams, who was on the Obama campaign’s national finance committee and previously a partner at high-powered lobbying firm Akin Gump. Burns was a registered lobbyist at Akin Gump from 1999-2007, a period during which he represented clients in the pharmaceutical industry including Merck, Pfizer, Human Genome Sciences, and Wyeth. From 2014-2017, he was a lobbyist for General Electric, where he lobbied mostly on trade and intellectual property issues.
Rich Weissman—former senior vice president at Bank of America
Wesisman hosted a fundraiser for Buttigieg at a private resort in Palm Springs on Nov. 20, the Intercept reported. Attendees who contributed more than $1,000 were invited to a “meet and greet” reception with the mayor, while those contributing at least $250 were given general access to the event. In 2013, Weissman joined the board of directors of the Log Cabin Republicans, “a Republican organization working to build a stronger, more inclusive Republican Party.”
That's not to speak of some of the people whose money Pete has returned:
Alexandra Walsh and Beth Wilkinson—attorneys at D.C. law firm Wilkinson Walsh + Eskovitz
Washington lawyers Walsh and Wilkinson represented Supreme Court Justice Brett Kavanaugh in his confirmation hearing amidst accusations of sexual assault by Christine Blasey Ford and other alleged victims. Buttigieg attended a July fundraiser co-hosted by Walsh, and in November the campaign told the Guardian US that it returned the law partners’ maximum donations and renounced their support.
Stephen R. Patton—lawyer with Kirkland & Ellis in Chicago
Patton led an effort to block the release of a video depicting the deadly shooting of African-American teenager Laquan McDonald, according to multiple reports. Following a public backlash after an Associated Press article identified Patton as a Buttigieg bundler, the Buttigieg campaign returned the contributions Patton had collected, as well as Patton’s own contribution, and cut ties before an Oct. 18 event.
