Sources said that Trump campaign senior communications adviser Jason Miller — along with female colleagues including senior adviser and surrogate A.J. Delgado and deputy communications director Jessica Ditto — went with several members of the media from networks, including CNN, NBC and ABC, to Sapphire Las Vegas Strip Club before the big night.

With “70,000 square feet of topless entertainment and serving the finest variety of cocktails,” Sin City’s Sapphire bills itself as the largest strip club in the world.

The group that went out with the Trump aides included CNN producer Noah Gray, NBC News reporter Anthony Terrell and a “camerman” from ABC News, sources said. Before the field trip with the media, Miller tweeted, “Yet more evidence of a media-rigged election,” with a link about WikiLeaks and Clinton.

A media insider said, “It was a pretty bad idea, especially the day before the final debate. It’s a serious lapse in judgment.”
