Operating Engineers Local 501 is attempting to turn up the heat in its organizing effort at Resorts World Las Vegas with a scathing letter to Gov. Steve Sisolak that accuses the casino’s owner Genting Group of maintaining “alarming” ties to Chinese Communist state-owned businesses.

“We are concerned that the findings … were not adequately considered during Resorts World/Genting Group’s licensing investigation by the Nevada Gaming Control Board and Nevada Gaming Commission,” Local 501 Director of Organizing Jose Soto wrote in an Aug. 3 letter copied to state legislative leaders and the heads of investigations at the Control Board as well as its executive secretary.
