Democratic presidential candidate Hillary Clinton made a surprise appearance at a protest outside Trump Hotel Las Vegas on Monday, the eve of the Democratic Party's first presidential debate. Hundreds of members of Culinary Workers Union Local 226, as well as Trump Hotel employees, rallied outside the hotel -- named for Republican candidate Donald Trump -- to protest the business' nonunion policy.

Clinton, the former U.S. secretary of state, reportedly told the hotel's workers they have the right to organize and the right to a living wage. "That means saying no to Donald Trump," Clinton said, the Las Vegas Sun reported.

The Culinary Workers Union has called for just and fair treatment of all workers, including immigrant workers, and is Nevada’s largest immigrant organization, with more than 55,000 members. The organization is approximately 55 percent female and 56 percent Latino, according to a news release. This year, Trump experienced a public backlash after he made inflammatory anti-immigration comments.

“Over 500 Trump Las Vegas employees, including many immigrants, are seeking to unionize in an atmosphere of neutrality and respect. The Trump Las Vegas workers want to have the American Dream and have a better life for themselves and their families. However, Trump Hotel management has responded with a vicious anti-union campaign,” according to the union.
