"All that we’re asking is that if Donald Trump lies, that it’s pointed out," said Mook on ABC's "This Week." "It’s unfair to ask that Hillary Clinton both play traffic cop with Trump, make sure that his lies are corrected, and also to present her vision for what she wants to do for the American people."

Mook called Trump "special," explaining that in past election cycles, presidential candidates have laid out extensive plans before the debate on what they would do as president. The Clinton campaign fears that Trump's lack of details about his plans has lowered expectations for how well he answers questions from debate moderator Lester Holt.

"I think Hillary is going to have to press the point. I think she’s going to have to at times challenge him to reveal what his plans are," Mook told ABC News' George Stephanopoulos. "This is a time for him to present those plans and maybe he will, but we’ll have to see."

Watch the first presidential debate Monday at 9 p.m. ET. Full live coverage and analysis of the debate will begin on at 7 p.m. ET.
