LAS VEGAS (AP) — Nevada's most influential union has not yet decided if it will endorse a candidate in the Democratic presidential race, but it's sending a subtle message to its members discouraging support for Bernie Sanders and Elizabeth Warren over their health care stances.

The casino workers’ Culinary Union began distributing leaflets in employee dining rooms this week that pushes back against “Medicare For All,” the plan from Sanders and Warren to move to a government-run health insurance system.

The leaflet said “presidential candidates suggesting forcing millions of hard working people to give up their healthcare creates unnecessary division between workers.”
