The Democratic-led Legislature and Republican Gov. Bruce Rauner are at odds over a proposal that would alter how Illinois distributes school money.

Legislators approved a required plan that re-writes the funding formula, but Rauner opposes it and says he’ll send it back with changes. Democrats are unsure if they have the votes to override him and are using a procedural hold to keep it off Rauner’s desk, at least until Monday.

In the meantime, Rauner has convened a costly special session, but no one has budged in the first few days. With the bill’s fate undetermined, it’s unclear when, or if, schools will get funding.
