From the New York Times:
Federal authorities discovered two more explosive devices, one addressed to Senator Cory Booker and the other to James R. Clapper Jr., the former director of national intelligence, law enforcement officials said on Friday. The package sent to Mr. Clapper was addressed to CNN’s offices in New York and was similar to a pipe bomb found Wednesday that was addressed to John O. Brennan, a former C.I.A. director. The discoveries came as investigators looking into a spate of pipe bombs sent this week have turned their attention to southern Florida.
The package sent to CNN was discovered on Friday morning at a United States Postal Service facility in Midtown Manhattan. The package for Mr. Booker, a New Jersey Democrat, was found in Florida, the F.B.I. said. A total of 12 packages have been found so far.
The #FBI has confirmed an 11th package has been recovered in Florida, similar in appearance to the others, addressed to Sen. Cory Booker.
