In September 2015, five men who had demonstrated outside of a Trump presidential campaign event at Trump Tower in New York City sued Donald Trump, alleging that Trump's security staff punched one of them. They also allege that Trump's security guards had been advised by city police that they were permitted to protest there. Several people videotaped the incident.[143][144]
In June 2015, the Culinary Workers Union filed charges with the National Labor Relations Board (NLRB), alleging that the owners of Trump Hotel Las Vegas "violated the federally protected rights of workers to participate in union activities" and engaged in "incidents of alleged physical assault, verbal abuse, intimidation, and threats by management".[145] In October 2015, the Trump Ruffin Commercial and Trump Ruffin Tower I, the owners of Trump Hotel Las Vegas, sued the Culinary Workers Union and another union, alleging that they had knowingly distributed flyers that falsely stated that Donald Trump had stayed at a rival unionized hotel, rather than his own non-unionized hotel, during a trip to Las Vegas.[4][145]
