New report details Secret Service security failures during the attempted assassination on President Donald Trump in Butler, Pennsylvania, as six agents face suspensions without pay.

The Secret Service suspended six staffers and adopted dozens of security changes in the aftermath of an assassination attempt on Trump a year ago.

CBS News was taken inside the Secret Service's James J. Rowley Training Center in Laurel, Maryland, to see the agency's newest eyes in the sky, a fleet of military-grade drones that reimagine aerial reconnaissance in a post-Butler era.
