A court fight in Arizona could determine the rights of states to stop funding Planned Parenthood.
The country's largest abortion provider filed suit Monday against Arizona to block enforcement of a law cutting off state dollars to its clinics.
Planned Parenthood claims the new law violates the rights of Medicaid patients who won't be able to get certain services elsewhere if funding stops.
"It is wrong for the state to tell Arizonans who they can and cannot see for their health care," Planned Parenthood Arizona President Bryan Howard said.
Conservative Arizona lawmakers are among others across the nation who say no federal funds should go to a group that provides abortions. Several states are adopting similar laws.
Another battle over abortion is playing out in Virginia, where Attorney General Ken Cuccinelli has refused to certify new abortion clinic regulations.
Virginia lawmakers voted to require abortion clinics to meet the same building standards as hospitals.
But pro-choicers opposed those standards, saying they would force most clinics in the state to close.
In response, the Virginia Board of Health revised the provision, exempting existing clinics from the requirement.
Cuccinelli said the Board of Health unlawfully changed the new abortion clinic rules.
The regulations still must go before Virginia Gov. Bob McDonnell, who could order the board to reconsider.
