The Kentucky Republican says he has written the FBI twice seeking the agency's rules for domestic drone use. He says he has told the FBI he'll put a hold on James Comey's nomination until his questions are answered.
Comey spent 15 years as federal prosecutor before serving in Bush administration. Obama has nominated him to replace outgoing FBI Director Robert Mueller.

He says Americans should know what privacy protections exist.
