WASHINGTON (Reuters) - Former U.S. Director of National Intelligence James Clapper, who was reportedly the target of a suspicious package found on Friday, said the spate of package bombs mailed to prominent Democrats and other critics of President Donald Trump are clearly acts of domestic terrorism.

Clapper, speaking in an interview on CNN where he works as an analyst, said he was not surprised that he was targeted and called the incidents “serious.”
