FBI won't comment on origin of suspicious packages
FBI Assistant Director William Sweeney would not confirm the origin of the packages delivered Monday, despite reports that investigators believe some of the packages might have originated in Florida.
He stressed that investigators must be careful with sharing information with the public, and that they could not “disclose information that could adversely impact our investigation or a future prosecution.”
"Some were obviously in the postal system. I'll leave it at that," he said in an ongoing news conference.
Phillip Bartley, inspector in charge of the US Postal Inspection Service in New York division, said more than 600,000 postal workers were looking for the packages.
"We have the eyes and ears looking for these packages," he said.
Ten packages have been found so far, Bartley added.
"I will say in the postal network, we have found nothing in the last eight hours," he said.

Trump calls New York Gov. Andrew Cuomo
President Trump called New York Gov. Andrew Cuomo Thursday and the two spoke about the ongoing investigation into the suspicious packages, Cuomo told CNN’s Brooke Baldwin.
“He pledged full support from all federal authorities,” Cuomo said, adding that he told Trump that he believes the state and federal government are working well together.
Asked if the President's rhetoric was a part of the conversation, Cuomo said: “The conversation with the President was only about the law enforcement and the investigation."
However, he added, "Yes, the President's rhetoric is inflammatory, it's hot. He uses really vulgar expressions at times and that has an effect... He's President of the United States and he has thousands of people listening to him and that position of power, I think, he has to appreciate. When that position of power is spewing hateful rhetoric, that has an effect."
