(Reuters) - Democratic presidential candidate Bernie Sanders, who bills himself as a champion of organised labour, found himself in an escalating feud with Nevada's Culinary Workers Union on Wednesday, 10 days before the state holds the party's third nominating contest.
Tensions have been simmering for months between the powerful 60,000-member union and the 77-year-old U.S. senator, who comes to Nevada after a strong showing in Iowa and victory in New Hampshire on Tuesday.
