President Trump will hold an event in Las Vegas. The president said this week that he’d be going to Nevada to thank voters. He’s the first Republican to win the state since Geroge W. Bush in 2004. And advisers say the president will offer details on keeping a campaign promise to exclude tips from federal taxes. He will give remarks in Las Vegas, a city which  is fueled by the hospitality and service industries, and where everyone from restaurant waiters to valet parkers to hotel maids relies on gratuities.
