Pipe Bombs Investigation Turns Toward Florida as More Trump Critics Are Targeted

Federal authorities investigating a spate of pipe bombs sent this week to several prominent critics of President Trump have turned their attention to southern Florida, believing that a number of the devices were mailed from there, two people briefed on the matter said Thursday.

The focus on Florida came as three more devices were found, the F.B.I. said. Two were addressed to former Vice President Joseph R. Biden Jr. in Delaware and a third to the actor Robert De Niro, who lives and works in Lower Manhattan.
