LITTLE ROCK, Ark. (AP) — The Arkansas Senate is scheduled to vote on an override of Gov. Mike Beebe's veto of a bill that would ban most abortions in the state at 20 weeks. The Senate is also to consider another bill that would prohibit the procedure at 12 weeks.

The Senate plans to vote Thursday on whether to override Beebe's veto of the 20-week ban. The House voted to override on Wednesday and if the Senate override vote is successful then the law takes effect immediately.

Beebe says the bill is unconstitutional and he's concerned about the legal costs of defending it.

The Senate also plans to vote on a separate bill to ban most abortions at 12 weeks. Beebe calls that measure unconstitutional, but hasn't said if he'll veto it.
