#Calexit: Is it possible for California to secede from U.S.

David Carrillo quoted by ABC 10, Nov. 9, 2016

“There is no legal basis for a state to secede from the union.” Carrillo said. “The U.S. Constitution (A4s3) has a procedure for adding new states or subdividing existing states–both require Congress to consent. But there is no procedure, at all, in the U.S. constitution for a state to secede.”
