Asked Monday whether he planned to participated in all three outings, Trump told reporters on his plane, "As of this moment, yeah," according to a video of the interview tweeted out by an NBC producer.

Pressed on what could cause him to change his mind, Trump replied, "Hurricanes, natural disaster …” before trailing off. 

"I expect to do all three," he said. "I look forward to the debates."

Trump also said he had no plans to conduct mock debate sessions in which somebody plays the role of Hillary Clinton. 

Such sessions are typical in traditional presidential debate preparation, but Trump prefers instead to have looser, cheeseburger-fueled sessions with top aides and informal advisers such as former Fox News chief Roger Ailes.

Trump said Monday he thought he had an "obligation" to debate Clinton and said the presidential debates are an "important element of what we're doing."
