Donald Trump and Sarah Palin will kick off a major conservative convention together on July 1 in Denver, organizers of the Western Conservative Summit announced Wednesday.

The former Alaska governor and 2008 vice-presidential candidate will speak, as will Trump on the first day of the summit, which bills itself as the "largest gathering of conservatives outside of Washington, DC." Organizers told The Denver Post that Palin's speech will be a half hour and Trump is slated to speak for an hour, though the order has not been determined.

Palin has made sporadic appearances alongside Trump since endorsing him in January ahead of the Iowa caucuses, including an unannounced stop in San Diego last month where she remarked that the presumptive Republican nominee "blew the lid off the corrupted and corroded machine."

"He was like a golden wrecking ball. He wrecked what needed to be wrecked," Palin said during the May 27 event.

Polling is scarce in Colorado, with the most recent Quinnipiac University poll conducted last November finding Trump with an 11-point lead over Clinton.
