CNN changed its rules on Tuesday for the next Republican presidential debate in a way that could give former business executive Carly Fiorina a chance to take the stage with the main contenders for the party's 2016 presidential nomination.

The cable network, which is sponsoring the Sept. 16 debate, said any candidate who ranks in the top 10 in polling since the first debate on Aug. 6 would be included in the next prime-time debate.

CNN originally had planned to include polling data dating to July 16 to determine the participants, but Fiorina criticized that plan because it would not have taken into account her surge in support since the first debate.
