The Clark County Education Association has thrown its support behind presidential candidate Bernie Sanders ahead of Nevada’s Democratic caucus in February. The union, which represents licensed educators from the nation’s fifth-largest school district, announced its endorsement of Sanders on Tuesday morning.

The Clark County School Board of Trustees approved a contract Thursday night with the union representing licensed educators, formalizing a tentative agreement reached last month amid threats of a teacher strike.

Teachers’ anger over an ongoing contract dispute rooted in promised pay raises boiled over during a public meeting Thursday evening that the Clark County School Board of Trustees ultimately cut short.
