MANHATTAN – Several buildings at Columbus Circle were evacuated Wednesday after police responded to a suspicious package at the Time Warner Center, CNN's headquarters in New York, the network reported.
The package, which is believed to contain a pipe bomb, was addressed to former CIA director John Brennan, who appears on the air on other cable and television transmissions, reports The Associated Press.
A New York City mobile emergency alert came out after 11 am, alerting people on West 58th Street between Eighth Avenue and Columbus to take shelter while law enforcement officers handled the possible explosive device.
The incident took place when officials confirmed that other packages were sent to former President Barack Obama's residence and to Chappaqua's home where the 2016 Democratic nominee Hillary Clinton and her husband, former President Bill Clinton, live. All the devices were intercepted.
An official of the law said that the devices destined to Obama and Clinton seem to be rudimentary but functional and similar to those sent to the house of the multimillionaire investor and the main Democratic donor George Soros, reports CNN.
Another law enforcement official told the AP that the explosive discovered Monday at the Soros suburban complex in New York was also a bomb.
The NYPD responded to the suspicious package at Columbus Circle just after 10 a.m.
The CNN newsroom was evacuated as a precaution, according to CNN.
The evacuation occurred when CNN reported on the other intercepted packages, and the moment was captured live on television.
The White House press secretary, Sarah Sanders, has published a statement about the incidents:
"We condemn recent attempts at violent attacks against President Obama, President Clinton, Secretary Clinton and other public figures. These terrorist acts are despicable, and all those responsible will be held responsible to the fullest extent possible by law. "The Secret Service of the United States and other law enforcement agencies are investigating and will take all appropriate measures to protect the people threatened by these cowards."
President Donald Trump and Vice President Mike Pence have also tweeted about the incidents:
On Monday, an explosive device was sent to the Soros' home in New York, authorities said.
Soros, who made his fortune in hedge funds, frequently donates to liberal causes and is vilified to the right, reports AP.
Despite Wednesday's reports that a suspicious package was also addressed to Governor Andrew Cuomo, his office tells PIX11 that no such package has been found.
CNN reports that it was initially told that there was also a pipe bomb aimed at the White House that was being examined at the external processing facilities that handle the White House mail.
Later, CNN took a step back in that report and declared that a suspicious package was never addressed to the White House.
When the police responded to Columbus Circle, New York police asked New Yorkers to remember to stay tuned and report suspicious devices and activities to the department's counterterrorism hotline at 1-888-NYC-SAFE (692-7233) or send an email to NYCSAFE@NYPD.org.
Cuomo, Mayor Bill de Blasio and Police Commissioner James O'Neill will hold an informational meeting at Columbus Circle around 12:45 p.m. Update this publication to get the latest information.
