Oklahoma has become the latest state to mobilize behind so-called "personhood" legislation, which would define the beginning of human life as at the moment of conception. The state Senate passed such a bill, 34-8, on Wednesday and it looks likely to sail through the House as well, the Oklahoman reports.

Virginia House legislators also passed a pair of anti-abortion bills this week, including its own personhood measure. The other bill would require women to have an ultrasound before undergoing an abortion. A version of the ultrasound legislation has already passed the state Senate and Republican Governor Bob McDonnell is expected to sign the bill into law, CBS News reports.
