In this regard, DOJ Civil Rights Division Senior Assistant Attorney General Pamela Karlan looks for indications of violations of federal law in her letter to state Senate President Karen Fann, a Republican senator, according to Business Insider, on May 6. 

In her letter, Karlan argues that the involvement of the team conducting the audit, Cyber Ninjas, could be illegal, and federal election records may not be being adequately safeguarded and preserved, which could be "at risk of damage or loss."

It also questions the Cyber Ninjas' goal to "identify voter registrations that did not make sense" and then knocking on doors to confirm whether valid voters actually lived at the stated address, presuming possible "voter intimidation."
