(CNN) - Rudy Giuliani is still considering a presidential bid and said on CNN's "Piers Morgan Tonight" he will make a decision by the end of September.
But the former New York City mayor and 2008 Republican presidential candidate said he is not "any closer to a decision."
"I don't think I've changed my thinking about it very much," Giuliani said Tuesday. "I'm interested to see Gov. Perry's entrance into the race and what that does and what he has to say."
