The Democratic governor, who submitted signatures this morning for his November ballot measure to raise taxes, declined to discuss the ballot measures on the June 5 ballot.
"Focus, focus," he said, telling reporters he is "sticking to the measure that we're filing signatures for today."
Proposition 28 would alter legislative term limits, allowing lawmakers to serve 12 years either in one house or divided between the Assembly and Senate. Lawmakers are currently restricted to eight years in the Senate and six in the Assembly.
Proposition 29 would impose an additional $1-per-pack tax on cigarettes to pay for cancer research and smoking cessation programs.
Brown's November initiative would raise income taxes on California's highest earners as well as the state sales tax rate.
"As governor, my responsibility is to balance the budget, protect our schools, protect public safety," he said today. "That's what I'm doing. I need to get this initiative passed, so that's my focus."
Philip Morris USA is among the most recent large contributors to Brown's re-election campaign, donating $26,000 last month.
