Hillary Clinton's super PAC is up and running with millions in the bank. Some of it comes from President Obama's biggest financial backers in 2012.

The group Ready for Hillary, created by supporters of the former secretary of state, raised $1.25 million in its first full quarter of existence. Its mission is to promote the still-non-existent presidential candidacy of Clinton, who is widely considered a top White House contender in 2016.

Today, the group released its list of donors.

While more than 10,000 people gave money to the group, its list of donors who gave more than $200 includes 20 people who also bundled campaign contributions for President Obama in 2012. They donated just over $200,000 to the pro-Hillary cause, after collecting a combined $10.8 million for Obama in the last election cycle.

The group is also backed by a number of prominent Clinton supporters and influential Democrats.

One notable Ready for Hillary donor is Jerry Lundergan, former head of the Kentucky Democratic party, friend of the Clintons, and father of Alison Lundergan Grimes, the Democratic secretary of state in Kentucky who is running for U.S. Senate against Senate Minority Leader Mitch McConnell. Lundergan gave the group $25,000.

Another $25,000 donor is James Hormel, of the Hormel Foods family and former U.S. ambassador to Luxembourg under President Bill Clinton. He was the first openly gay U.S. ambassador.

Former Hillary Clinton advisor Harold Ickes gave $2,500. Ellen Tauscher, the former Democratic congresswoman and State Department envoy on missle defense, gave $2,500. Both Ickes and Tauscher publicly signed on with Ready for Hillary.

American Federation of Teachers President Randi Weingarten gave $1,000, as did Democratic analyst Hilary Rosen. Pollster Celinda Lake also gave $1,000, as did Arab American Institute founder James Zogby. Former Democratic Michigan governor Jennifer Granholm, who also has expressed her public support for Hillary Clinton in 2016, gave $500.
