On May 20, Fox News announced the rules on who will be invited into the August 6, 2015 Republican presidential debate. Also on May 20, CNN announced the rules for the September 16 debate. The Republican National Committee had earlier decided not to set any rules, and to let the networks sponsoring the debates make the rules.

The August 6 Fox debate will invite the top ten candidates, as measured by polls. The CNN September 16 debates will be in two parts. One will be for the top ten candidates, as shown by polls. The other debate will be for those who weren’t included in the first debate but who are at least 1% in polls. See this story.

Earlier in the day, Newt Gingrich had said in a news interview that he believed the party should include all the candidates, even if that meant holding two debates, with candidates randomly put in one or the other. See this story.
