ALPINE, N.J. -- Preliminary tests on a suspicious envelope sent to the Alpine home of Kellyanne Conway, a top adviser to President Trump, "indicated no threat to public safety," an FBI spokesman told Daily Voice early Wednesday.

The FBI, as per protocol, didn't identify Conway as the recipient.

However, Conway told Fox News host Sean Hannity on Monday night that she'd been assigned Secret Service protection after receiving the suspicious delivery -- which she blamed on negative press coverage of the president.

“We have packages delivered to my house with white substances," Conway said on the Hannity program. "That is a shame.”

As a precaution, the FBI sent the envelope to a New Jersey State Police laboratory for further testing.

"The FBI encourages the public to remain vigilant and report all such instances immediately," said Michael Whitaker of the bureau's Newark Field Office.
