Senator Rand Paul issued a letter to FBI Director Robert Mueller seeking answers about the FBI's domestic use of drones. In a Senate Judiciary Committee hearing on FBI oversight, Director Mueller admitted that the FBI uses drones for domestic surveillance. Mueller also stated there were no guidelines in place to regulate the FBIs use of drones and protect the privacy of Americans. EPIC petitioned the Federal Aviation Administration last year to conduct a public rulemaking to address the threat to privacy and civil liberties the domestic use of drones pose. EPIC also petitioned the Bureau of Customs and Border Protection this year to establish privacy regulations for its use of drones.
