Trump Campaign in Change of Tone Calls Debate Moderator ‘Brilliant’

Trump had said moderator would be under pressure to be tough on GOP candidate.

"He’ll do a good job tomorrow night as a moderator," Conway said of Lester Holt.

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

The Clinton campaign has been pushing for moderators to act as a truth squad.

"All that we're asking is that if Donald Trump lies that it is pointed out," Clinton campaign manager Robby Mook said on "This Week."

Conway, in her appearance on "This Week," disagreed. She said moderators should stay out of the fray and not challenge candidates in instances where they may be bending, or breaking, the truth.

"I really don't appreciate campaigns thinking it is the job of the media to go and be these virtual fact-checkers and that these debate moderators should somehow do their bidding," she said.

Asked about her expectations of the event, she said: "We certainly hope this debate tomorrow night will be about substantive issues."

"A victory for Donald Trump tomorrow night is answering the questions and showing America that he's ready to be president and commander-in-chief on day one," she concluded.
