LAS VEGAS (AP) " The latest on the 2020 presidential campaign (all times local):

11:15 a.m.

Democratic presidential candidates are joining union members picketing outside a Las Vegas casino.

Elizabeth Warren arrived first Wednesday at the Palms Casino Resort off the Strip. Wearing red like the picketing workers of the powerful Culinary Union, Warren marched with workers. She joined in chants of 'Palms Casino look around, Vegas is a union town.'

Pete Buttigieg carried a Culinary sign saying 'No contract, no peace' as union officials pushed through a throng of television cameras to clear a path for him along the picket line. Amy Klobuchar carried a sign for the Teamsters.

Joe Biden wrapped an arm around Culinary leader Geoconda Argüello-Kline. Tom Steyer joined in chants of 'No justice, no peace,' bobbing his head to the rhythm.

Workers at the Stations Casinos, a chain of neighborhood establishments, and the Palms have voted to join a union but are still working without contracts. The owners are billionaires Frank and Lorenzo Fertitta, who are staunch supporters of President Donald Trump.

Bernie Sanders, who has feuded with union leaders after they warned members that his 'Medicare for All' plan would jeopardize their vaunted health care, did not join the picket.
