The former Alaska governor and vice presidential candidate turned media personality will join Republican presidential nominee Donald Trump at the Western Conservative Summit in Denver.
Summit organizers announced Sarah Palin's appearance Wednesday in a press release that called Palin's endorsement one of the most influential and sought after in Republican politics.
The Western Conservative Summit, considered the largest gathering of conservatives outside of Washington, D.C., runs July 1 to July 3 at the Colorado Convention Center, just a few weeks before the Republican Convention July 18-21 in Cleveland.
Palin, a Trump supporter who has appeared with him numerous times, will speak Friday morning during the same session as Trump.
Palin also attended the summit in 2014.
