Two megadonors accounted for almost two-thirds of the contributions to the main super PAC supporting Hillary Clinton in July, as the group's income slowed slightly from the month before.

Investors Daniel Abraham and Donald Sussman each gave $3 million to Priorities USA Action. The super PAC's total haul was $9.9 million, down from $11.9 million in June. The group finished July with $38.7 million cash on hand.


The super PAC has been spending aggressively on a torrent of ads attacking Republican nominee Donald Trump, including about a half-million on ads over the next two weeks.

The latest gift makes Sussman, the founder of Paloma Partners in Greenwich, Connecticut, the group's biggest benefactor this cycle, with $11 million to date, overtaking Univision Chairman Haim Saban and his wife, Cheryl. Abraham, who founded the company behind Slim-Fast, has given $6 million.

The next-biggest donors in July were the Laborers' International Union of North America (LiUNA) PAC, at $1 million, and Ann Doerr, wife of venture capitalist John Doerr, and medical technology heiress Pat Stryker, each with $500,000.

Other repeat donors include Jay Robert and Mary Kathryn Pritzker, with $450,000 each, and billionaire investor George Soros, with $35,308.50.

Priorities USA transferred $1.9 million to the Women Vote super PAC, $655,000 to VoteVets, and $500,000 to the Philadelphia 2016 Host Committee, which organized the Democratic National Convention.
