On Tuesday, the campaign sent an email to supporters in California inviting them to a July 13 training session for the “Trump Leadership Initiative (TLI) Fellowship Program” in the city of Stanton, in Orange County.

“TLI Fellows are the backbone of the Trump strategy to launch the largest, earliest, and most diverse ground operation in California history,” the email states. “Fellows will be trained and experienced in grassroots organizing, field operations, cutting-edge campaign technology, messaging & communications, and engaging in voter contact.”
