AUSTIN, Texas -

A spending bill crucial to a complex Texas budget deal contains an extra $200 million to public schools as pledged by Senate negotiators.

The bill unveiled late Wednesday has created a standoff between the House and Senate during what has been a tense final week of the 140-day legislative session. House Democrats were wary of the Senate keeping classroom spending in the bill.

The House was reluctant to take action on a separate -- but equally crucial -- component of a multilayered budget compromise until seeing the Senate measure.

Both chambers were expected to take up the key bills late Wednesday night.

The Legislature must come to an agreement on a new state budget before adjourning Monday. If not, Gov. Rick Perry will haul lawmakers back for a special session.
