California is a little bit closer to providing universal preschool for all its four-year-olds. 

Senate Leader Steinberg's plan to expand pre-kindergarten passed a committee hurdle today.

It would allocate one and a half billion dollars to offer up the preschool classes to students of parents who otherwise couldn't afford them.

He says we're not just talking about adding another year of school here. 'We're talking about brain development and early childhood education from zero to five, so that when kids enter kindergarten, they are ready,' he says. 

Some private preschool operators are opposed to the plan, worried they'd lose business. Republican leaders are also skeptical, citing the very high cost. It would be phased in over five years.
