"He certainly has a plan," Conway said on MSNBC's "Morning Joe." "I've heard it."

Conway said Trump may offer some details at the first presidential debate Monday evening.

"This is his debate tonight. ... He'll tell you if that question is asked," Conway said, when pressed.

Later in the interview, she attempted to clarify what Trump might reveal.

"You will get his view of how best to defeat the enemy without telling ISIS specifically what it's going to be," Conway said.

Conway also criticized Democratic presidential nominee Hillary ClintonHillary Diane Rodham ClintonIntel Dem decries White House 'gag order' after Bannon testimony 'Total free-for-all' as Bannon clashes with Intel members Mellman: On Political Authenticity (Part 2) MORE for publicizing her plan to defeat ISIS on her campaign website.

"Is it that ISIS can't read that plan?" Conway asked.

"Here's what we know. We know that since 2003, ISIS and its predecessors have been responsible for about ... 33,000 deaths. Eighty percent of them have occurred in just the last three years under ISIS.

"So, people know the birth and the growth of ISIS have occurred on President Obama's watch, if not Secretary Clinton's."

During a rally earlier this month, Trump said he would order the military to come up with a plan to defeat ISIS "in 30 days" if he becomes president.

“I am going to convene my top generals and give them a simple instruction: They will have 30 days to submit to the Oval Office a plan for defeating ISIS,” Trump said.

He often says the U.S. needs to be tough to defeat ISIS but has declined to give details about his plan to defeat the militant group.
