Democratic Assemblyman Luis Alejo says he introduced the bill because of a conflict between the new state pension law and U.S. labor law that applies to 20,000 local and regional public transit workers.  As a result, he says, two billion dollars in federal transportation funds are at risk.

Alejo: "If there's a way we can fix this, then I'm open to doing that.  But there's a major problem that's before the state right now and nobody has fixed it so far and projects are getting held up." 

But Republican Assemblyman Allan Mansoor says Californians approved Governor Jerry Brown's tax measure last fall believing the state's pension changes were real.

Mansoor: "I can't support anything that's going to move California backwards in terms of reform.  I feel like that would be a double-cross on the voters."

Brown's press secretary says any new legislation should "not in any way weaken" last year's changes.
