Not long after, it was announced that a ninth suspected bomb was discovered on its way to former Vice President Joe Biden in DE, a claim since confirmed by the Federal Bureau of Investigation. Debbie Wasserman Schultz of Florida, the sources said. She is the former chairwoman of the Democratic National Committee who was accused by Clinton rivals of secretly helping the party's eventual presidential nominee.
There were also reports of another suspicious package being discovered outside the building that houses the office of Senator Kamala Harris, a California Democrat, as well as the San Diego Union-Tribune newspaper.
Although the President has often derided the media as "fake news", even labeling reporters the "enemy of the people", Thursday's tweet is especially striking in the wake of potential attacks on a major media outlet and political figures who have criticized him.
The facility was evacuated while authorities investigated.
"The building is open and everybody is safe", she told CNN.
Another suspicious package, similar to the ones sent to Barack Obama, Hillary Clinton, Joe Biden and Bill Clinton on October 24, was intercepted in New York City in the early hours of October 25. The package contained a pipe bomb and was addressed to De Niro, whose Tribeca Productions shares the restaurant's address. Both are associated with the actor and filmmaker Robert De Niro, who has been a critic of President Donald Trump.
"X-ray images show that the package addressed to De Niro contains a device similar to the pipe bombs found in other packages this week that were addressed to prominent critics of Trump, the two sources said", CNN reported.
Earlier in the week, a pipe bomb was left in the mail box of billionaire philanthropist George Soros' New York home.
The package contained an envelope of white powder that experts were analysing, Police Commissioner James O'Neill said.
The packages were mailed in manila envelopes with bubble wrap interior. An official said it was suspected to have been delivered earlier this week. The package is considered suspicious, but no details have been revealed except that it was misaddressed and returned to sender.
"I got the alert on my phone like stay clear stay away from windows and so on", said Harlem resident Samantha Brugger. "That suggests he's really focused on her".
Leading Democrats called the threats a symptom of a coarsening brand of political rhetoric promoted by Trump, who also condemned the acts but blamed the media, his frequent foil, for much of the angry tone of the time. "The language of moral condemnation and destructive routine, these are arguments and disagreements that have to stop".
Trump's words didn't satisfy his political opponents, however.
There has been no claim of responsibility.
