Manchester is a real-estate developer in San Diego who has reshaped portions of that city's waterfront, but he's even better known in Southern California for his onetime ownership of the San Diego Union-Tribune. Under his ownership, the newspaper moved to promote the city and advocate for a "pro-business, pro-military" agenda.

In Hillary Clinton's Corner

Haim Saban and family: $10.1 million

Egyptian-born Haim Saban started out promoting tours in Israel, ran a French record label and, after moving to Los Angeles in the 1980s, brought the children’s Power Rangers television show to the U.S. Saban partnered with Rupert Murdoch to form Fox Family Worldwide, which they sold to Walt Disney in 2001 for $3 billion. Saban used the proceeds to start Saban Capital Group, which has partnered on deals to acquire majority stakes in Israeli telecom firm Bezeq and Univision, the largest U.S. Spanish language television network. Saban, who’s worth about $3.6 billion, first donated to Bill Clinton in 1995 and has been a loyal supporter of the Clintons ever since, including more than $10 million in donations to the Clinton Foundation. Since 2003, the Sabans have contributed $15.5 million to federal candidates and committees.

J.B. Pritzker and family: $8.3 million

An heir of the Pritzker family hotel and manufacturing empire, Jay Robert Pritzker runs the Chicago-based Pritzker Group, a private equity and venture capital firm, with older brother Tony.

Pritzker has a net worth of $3.6 billion, according to the Bloomberg Billionaires Index. The Pritzker's family foundation has co-sponsored Clinton Global Initiative meetings and gave more than $10 million to the Clinton Foundation, which tapped J.B. Pritzker to serve on the leadership council of Too Small to Fail, an early childhood health project launched by Hillary Clinton. The Pritzkers have contributed $9.7 million to federal candidates and committees since 2003, with the bulk of their giving coming in the current election cycle.

Donald Sussman: $8.1 million

Donald Sussman operates Connecticut-based hedge fund Paloma Partners, which he started in 1981. Early investors included members of the Tisch family, owners of the CBS Television Network, Lollilard Tobacco and Loews Corporation. Sussman didn't become a major political donor until 1996, but his giving accelerated after marrying Chellie Pingree, a Democrat who was president of campaign-finance watchdog Common Cause before representing Maine's 1st district. Sussman and Pingree announced they were divorcing in 2015, but he remains active as a donor, a member of the Democracy Alliance network of progressive donors and on the board of the Center for American Progress, the liberal think tank. John Podesta, Clinton's campaign chairman, also serves on the board. Sussman has given $21 million to federal candidates and committees since 2003.
