A federal lawsuit is challenging Alabama's policy of stripping convicted felons' of their right to vote. The Greater Birmingham Ministries and 10 Alabama residents who aren't allowed to vote because of a past felony conviction filed the lawsuit Monday in Montgomery federal court. The lawsuit quotes 2014 statistics from the Sentencing Project that estimated more than 260-thousand people were blocked from voting in Alabama. Nearly half were African-American. The Alabama attorney general's office did not have an immediate comment. A spokesman for Alabama Secretary of State John Merrill said the office has a policy of not commenting on ongoing litigation.
