SACRAMENTO (AP) — State Assemblyman Brian Nestande resigned Tuesday from a Republican leadership post after providing the lone GOP vote on a bill that would close a tax loophole for out-of-state corporations. The bill, AB1500, which would eliminate a $1 billion tax break and use the expected windfall to reduce college tuition, passed the Assembly on Monday without a vote to spare. "I understood when I made the vote that I would have to step down," said Nestande, R-Palm Desert, referring to his previous position as chairman of the Assembly Republican Caucus.
