Another supporter helping Buttigieg, Adam Barth, is a Houston-based partner at McKinsey and Co., the management consulting firm where Buttigieg once worked. Barth does not have any significant history donating to federal campaigns, according to campaign finance records.

Other notable Democratic donors serving as Buttigieg bundlers include Susie Tompkins Buell, a major supporter of Hillary Clinton in 2016; Laurie David, a documentary filmmaker; Bryan Rafanelli, another major Clinton supporter; Tod Sedgwick, a former U.S. ambassador to Slovakia; and Rep. Don Beyer (D-Va.), a wealthy auto dealer who was the first member of Congress to endorse Buttigieg earlier this year.

The roster includes a number of former fundraisers for Hillary Clinton and Barack Obama — but it is heavy on bundlers who did not raise big money for the previous Democratic presidential nominees.

The publication of Buttigieg’s bundler list came after Buttigieg and Warren traded a week’s worth of attacks over transparency, each accusing the other of not being forthcoming about aspects of their campaigns and past employment. Warren, who has forgone private fundraising events altogether, criticized Buttigieg for his private events and for not releasing his Bundler list since April. Buttigieg, meanwhile, has needled Warren for not disclosing her pre-2008 tax returns detailing legal work she did for corporate legal clients, though she released the client list and the amount of money she made from them.

Warren sharpened her attacks against Buttigieg and Joe Biden in recent days, culminating in a blistering speech on Thursday when she targeted both her opponents for giving donors “regular phone calls and special access.”

“When a candidate brags about how beholden he feels to a group of wealthy investors, our democracy is in serious trouble,” she said in the speech.

Buttigieg responded Friday, criticizing Warren for setting up a “process purity test” around fundraising.
