AFP last month notched a big win when it got New Jersey Gov. Chris Christie to drop out of the 10-state cap-and-trade program for power plants. Now, AFP is looking for more states to take Christie's lead.

Mike Proto, the group's spokesman, said Cain is the only GOP White House contender to accept a request to speak at the rally, which coincides with one of RGGI’s emission allowance auctions. "Invitations are extended to all the presidential candidates," he said.

Conservative talk radio host Steve Malzberg is also expected to speak at the rally.
