ABC News announced Thursday it will exclude Carly Fiorina from the eighth GOP debate Saturday night.
Unlike previous debates, the upcoming one will not feature an "undercard" debate for low-polling candidates, which Fiorina was assigned for most of her debate appearances.
Candidates for the Saturday debate were required to finish in the top three in Tuesday's Iowa caucuses, the top six in New Hampshire polls or top six in national polls. Fiorina finished seventh in Iowa and is currently ranked eighth in the Washington Examiner's presidential power rankings.
The former Hewlett-Packard CEO had written a letter to the Republican National Committee on Wednesday encouraging party officials to amend the debate rules so that she could be included in the televised event.
"Networks are making up these debate rules as they go along — not to be able to fit candidates on the stage— but arbitrarily to decide which candidates make for the best TV in their opinion," Fiorina wrote. "Now it is time for the RNC to act in the best interest of the party that it represents."
Fiorina's campaign has not responded to the news.
Former Virginia Gov. Jim Gilmore, ranked last in polls, also will be excluded from the debate. He has regularly polled in national surveys at less than 1 percent.
Saturday's debate will include Jeb Bush, Ben Carson, Chris Christie, Ted Cruz, John Kasich, Marco Rubio and Donald Trump.
