U.S. Centers for Disease Control and Prevention (CDC) Director Tom Frieden is seen on a monitor as he testifies before the House Committee on Energy and Commerce Oversight and Investigations Subcommittee hearing on "Review of CDC anthrax Lab
Incident" on Capitol Hill in Washington July 16, 2014. U.S. lawmakers said on Wednesday there was evidence of a "dangerous pattern" of safety lapses at government laboratories dealing with dangerous pathogens such as anthrax and avian flu that required a change in culture at the U.S. Centers for Disease Control and Prevention.
