Two more suspicious packages found in US

Authorities have intercepted suspicious packages intended for Sen. Cory Booker and former Director of National Intelligence James Clapper, authorities said Friday.

The packages are the latest to be sent to prominent Democrats and critics of President Donald Trump that were discovered earlier this week.

Law enforcement authorities are treating the bombs as a domestic terror matter. The motive is unknown, but the recipients are all prominent targets of right-wing criticism and, in many cases, of Trump himself.

Clapper, who has frequently criticized Trump, vowed to CNN Friday morning that he wouldn't be intimidated in light of the discovery.

After another suspicious package was sent to a Manhattan post office, the city quickly warned residents to avoid the area.

New York City sent out an alert at 8:41 a.m. via the city's NYC Alert system.

"Due to police activity, expect traffic delays and a heavy presence of emergency personnel in the area of West 52nd Street and 8th Avenue, Manhattan," the alert read."

The package addressed to Sen. Cory Booker, of New Jersey, was addressed to his Camden office. It was intercepted in Florida, sources say.

The second package addressed to ex-national intelligence chief James Clapper via CNN was found in New York post office.
