—President Donald Trump said the media has a "major role to play" in culpability for the spree of 14 suspicious packages that were mailed to prominent figures.
—Cesar Sayoc, 56, of Florida, was arrested for allegedly carrying out a suspected mail bombing campaign this week, sources said. He was charged with five federal crimes, the U.S. Department of Justice announced Friday afternoon.
—Sens. Kamala Harris and Cory Booker, as well as former Director of National Intelligence James Clapper and billionaire philanthropist Tom Steyer, are the latest high-profile figures to be targeted, sources said.
—South Florida appears to be point of origin for some of the 14 suspected mail bombs, sources said.
A suspect was arrested in Florida for an apparent mass mail bombing spree that targeted top Democrats and other prominent figures across the country, officials said.
Cesar Sayoc, 56, of Aventura, Florida, allegedly carried out the widespread plot and triggered a nationwide manhunt, multiple law enforcement sources told ABC News.
The charges against him include interstate transportation of an explosive, illegal mailing of explosives, threats against former presidents and certain other persons, threatening interstate communications, and assaulting current and former federal officers, U.S. Attorney General Jeff Sessions said at a news conference Friday afternoon.
Sayoc faces up to 48 years in prison if convicted, a Justice Department spokeswoman told ABC News. He made no formal statement upon his arrest and gave no information as to how many more packages may be out there, law enforcement officials briefed on the case told ABC News.
