DENVER -- The case of the Aurora teacher who made comparisons between President George W. Bush and Adolf Hitler has now hit the state Legislature.

State senators are considering whether to give school districts greater protection to fire teachers who present biased views in the classroom. It wouldn't apply to teacher Jay Bennish, only future cases.

The Cherry Creek School District is investigating Bennish's comments. A recording of 20 minutes of his lecture has been made public but he has said the rest of the 50-minute class balanced out those comments.

State Sen. Doug Lamborn saif school districts may fear lawsuits if they fire teachers for presenting unbalanced views. The Colorado Springs Republican is trying to amend a teacher license bill to add showing a pattern of failing to provide balanced viewpoints is grounds for dismissal.

Under current law, the reasons a teacher can be fired include a physical or mental disability, immorality, unsatisfactory performance, insubordination or conviction of a felony.

A vote on Lamborn's amendment was delayed Thursday to give lawmakers time to think about adding it on to the bill.
