OKLAHOMA CITY (AP) State lawmakers already have filed several anti-abortion bills to build on restrictions approved by legislators in recent years. Federal statistics show about 7-thousand abortions have been performed in Oklahoma each year during the past decade. Oklahoma lawmakers passed several anti-abortion measures in 2005 and 2006, including provisions requiring written parental consent for a minor to have an abortion. It has yet to be seen if those changes have led to a reduction in abortions in Oklahoma. Republican state Senator Brian Crain wants to change the legal definition of abortion to include the practice of using drugs to kill a fetus before it is removed. Another measure Crain expects to file next week would prohibit insurance companies from covering state employees for abortion procedures. Posted at 1/15/2007 12:29:00 PM
