Arizona Republic PHOENIX — The U.S. Department of Justice's Civil Rights Division is asking Arizona Senate President Karen Fann to respond to concerns the department has about the security of ballots and potential voter intimidation as the Senate's contractors perform an audit of November's presidential election in Maricopa County. In a letter sent to Fann on Wednesday, Pamela S. Karlan, principal deputy assistant attorney general in the division, asked for Fann's response to its concerns with an explanation of "the steps that the Arizona Senate will take to ensure that violations of federal law do not occur" during the audit.
