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 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 package for Brennan was found at CNN’s offices in Midtown Manhattan.

The discoveries came as investigators looking into a spate of pipe bombs sent this week have turned their attention to southern Florida, believing that a number of the devices were mailed from there and passed through a mail facility near Miami, two people briefed on the matter said Thursday.

The package addressed to Clapper at CNN was discovered on Friday morning at a United States Postal Service facility in Midtown Manhattan, a few blocks south of the news network’s building. The package for Booker, a New Jersey Democrat, was found in Florida, the F.B.I. said.

A total of 12 packages have been found so far. All of them have been addressed to prominent critics of President Trump, including former President Barack Obama; former Vice President Joseph R. Biden Jr.; former Secretary of State Hillary Clinton; Representative Maxine Waters of California; former Attorney General Eric Holder; the actor Robert De Niro; and George Soros, the billionaire Democratic donor.

All of the envelopes had return address labels bearing the misspelled name of Representative Debbie Wasserman Schultz, a Democrat whose district is in southern Florida.

The first package was discovered on Monday afternoon at the suburban New York home of Soros. While investigators initially thought that some devices were hand delivered, they now believe it is likely all of them were sent in the mail. Using information collected by the United States Postal Service, investigators have focused their attention on certain Florida postal centers, including one in Opa-locka near Miami.
