A super PAC formed to support Cory Booker�s Democratic presidential campaign is shutting down.

The group�s founder, San Francisco lawyer Steve Phillips, indicated in a news release Wednesday that Dream United had struggled to raise money. Booker, a New Jersey senator, has publicly disavowed support from super PACs, which aren�t required to disclose their donors publicly.

Phillips, a former college classmate of Booker�s, said that it became clear while trying to fundraise for Dream United �that the donor community is strictly adhering to Senator Booker�s publicly articulated wishes that he does not welcome independent support.� The group raised a little over $1.1 million during the first six months of the year, far short of Phillips� stated $10 million goal.
