A 56-year-old man has been arrested in Florida in connection with a mail-bombing campaign aimed at critics of President Trump, US media say.
Twelve packages have been sent to figures such as former president Barack Obama and actor Robert de Niro in recent days.
The latest two were found in Florida and New York City on Friday.
The incidents come less than two weeks before the US mid-term elections, with politics highly polarised.
The FBI has reportedly been searching a mail facility in Florida for clues about the packages.
Mr Trump has commented several times on the incidents, but in his latest tweet he suggested the incidents, which he described as “‘Bomb’ stuff”, were slowing Republican “momentum” in early voting.
