Planned Parenthood is suing Arizona over a new state law barring the group from contracting with Medicaid because it provides abortions.

The law, championed by social conservatives, goes into effect on Aug. 2. Planned Parenthood says it will deprive thousands of low-income women from receiving care at their preferred medical provider.

"The men and women of this state have the right to see the healthcare provider they deem is best for them," said Bryan Howard, President and CEO of Planned Parenthood Arizona. "It is wrong for the state to tell Arizonans who they can and cannot see for their healthcare."

The law and subsequent lawsuit are the latest developments in what has become a nationwide battle between abortion-rights opponents and Planned Parenthood.
