October 2018 United States mail bombing attempts
The United States Secret Service intercepts two suspicious packages described as "potential explosive devices" addressed to former President Barack Obama and former Secretary of State Hillary Clinton. One addressed to former CIA director John O. Brennan was received at CNN's New York studios, which were evacuated. Other politicians who received similar packages include U.S. Representatives Debbie Wasserman Schultz (whose name and address was on the return label of a package meant for former Attorney General Eric Holder but had the wrong recipient address) and Maxine Waters. Authorities are also attempting to locate a suspicious package sent to former Vice President Joe Biden that was marked return to sender due to a bad address.
