The July 8 event, organized by Trump’s Save America political action committee (PAC), will take place at the Treasure Island hotel and casino. Lombardo and Laxalt are scheduled to hold a panel discussion at 5 p.m., while Trump is scheduled to give a speech at 6 p.m.

During the speech, Trump will “deliver remarks on the America First Agenda,” according to the PAC’s announcement. In addition to Trump, Lombardo and Laxalt, “additional special guests” will make an appearance.

It was not immediately clear if members of the public will be able to attend in person, but the Right Side Broadcasting Network will live stream the event on YouTube. Tickets available for purchase were not available on Trump’s official website as of Thursday afternoon.

Lombardo, sheriff for Nevada’s Clark County, is running in the state’s gubernatorial race against incumbent Democratic Governor Steve Sisolak. Lombardo won the Republican primary in June, beating fellow GOP candidate Joey Gilbert by about 11 percentage points, 38.4 percent to 27.6 percent.

FiveThirtyEight, which provides poll averages that take into account quality, sample size, recency and any partisan leanings, found that Sisolak was leading Lombardo by 2.1 percentage points as of June 15.

Laxalt is running with the hopes of unseating Democratic Senator Catherine Cortez Masto. He won his GOP primary in June with more than 50 percent of the vote, while Cortez Masto won the Democratic primary by a wide margin with about 90 percent support.

A poll conducted from June 24 to June 27 by Future Majority found that Cortez Masto was leading Laxalt by three percentage points, 46 percent to 43 percent.

Both Lombardo and Laxalt have received coveted endorsements from Trump.

“As governor, Joe will fiercely protect our under-siege Second Amendment, oppose sanctuary cities, support our Law Enforcement, veto any liberal tax increase, protect life and secure our elections,” Trump wrote in his endorsement for Lombardo.

In his endorsement for Laxalt, Trump described the candidate as a supporter of law enforcement and someone who has “fought valiantly” against election fraud.

“He is strong on Secure Borders and defending America against the Radical Left,” Trump’s statement read. “Adam has my Complete and Total Endorsement!”

The day after his Las Vegas speech, Trump will travel to Anchorage, Alaska, for a rally in support of several Republicans: U.S. House candidate Sarah Palin, U.S. Senate candidate Kelly Tshibaka and Alaska Governor Mike Dunleavy.
