Hours after CNN's New York City headquarters were evacuated over an explosive device Wednesday, the network's president, Jeff Zucker, issued a statement condemning President Trump and White House Press Secretary Sarah Sanders, saying they "should understand their words matter."

Zucker decried what he called the administration’s “continued attacks on the media.”

The statement continued: “The President, and especially the White House Press Secretary, should understand their words matter. Thus far, they have shown no comprehension of that.”

Police say an envelope containing a live explosive and “some kind” of white powder was sent to the network’s headquarters at the Time Warner Center in midtown Manhattan forcing an evacuation.

Similar packages were intercepted en route to the homes of former President Barack Obama and former Secretary of State Hillary Clinton. Another package arrived at a Florida office of Rep. Debbie Wasserman Schultz, the former head of the Democratic National Committee. And, a similar package arrived at the home of Democratic megadonor George Soros earlier this week.

U.S. Capitol Police also were investigating a suspicious package addressed to Rep. Maxine Waters, D-Calif., at the Capitol Hill mail screening facility.

A law enforcement official told Fox News that many of the devices have a similar packaging and labeling, leading them to believe a single person or group could be behind the threats.

Trump responded to news of the devices earlier, saying “the safety of the American people is my highest and absolute priority.”

“The full weight of government is being deployed to conduct this investigation and bring those responsible for these despicable acts to justice,” he continued.

Sanders and Vice President Mike Pence also took to Twitter to condemn the threats.
