Rep. Jason Frierson made history Monday by becoming Nevada’s first black Assembly Speaker as the state’s 63 lawmakers opened their legislative session focusing on issues ranging from the state budget to the future of an unimplemented law that would give parents state funding to help pay for private school. Frierson, D-Las Vegas, was elected to lead the Legislature’s lower chamber as lawmakers started work in the session that lasts until June 5. It also marked the first time that both the state Assembly and Senate will be led at the same time by black legislators.
