Several of President-elect Donald Trump‘s planned Cabinet nominees and administration appointees were subjected to bomb threats and “swatting” attacks Tuesday night and Wednesday morning, a spokesperson for the Trump transition team said.

The nominees and appointees “were targeted in violent, unAmerican threats to their lives and those who live with them. These attacks ranged from bomb threats to ‘swatting,’” transition spokeswoman Karoline Leavitt said in a statement.

Swatting is when a hoax call is made to police claiming a life-threatening situation is taking place. It is meant to draw SWAT teams to a location and can lead to deadly outcomes.

Three senior law enforcement officials briefed on the swatting incident involving multiple Trump allies told NBC News that these were not credible threats. No devices or physical threats were found and some of the threats may have come in over social media, the officials said. The threats did not involve U.S. Secret Service protectees such as Trump or Vice President-elect JD Vance.

The FBI said in a statement it “is aware of numerous bomb threats and swatting incidents targeting incoming administration nominees and appointees, and we are working with our law enforcement partners. We take all potential threats seriously, and as always, encourage members of the public to immediately report anything they consider suspicious to law enforcement.”

The Trump statement did not identify exactly who or how many incoming officials were subjected to the hoax but said “law enforcement and other authorities acted quickly to ensure the safety of those who were targeted.”

“President Trump and the entire Transition team are grateful for their swift action,” the statement said.

The office of Rep. Elise Stefanik, R-N.Y., Trump’s nominee to be ambassador to the United Nations, said she was one of the targets.

The office said in a statement that Stefanik, her husband and their three-year-old son were driving home from Washington “when they were informed of a bomb threat to their residence. New York State, County law enforcement, and U.S. Capitol Police responded immediately with the highest levels of professionalism.”

Former Rep. Matt Gaetz, R-Fla., who last week withdrew his bid to be Trump’s attorney general, confirmed that he was among the targets of a bomb threat. A bomb squad reported to his home in Florida in response to the threat. Initially, a bomb-sniffing dog was brought to his home by the sheriff but was inconclusive, which led to the bomb squad being called in.

The Okaloosa County Sheriff’s Office said “no devices were located. The immediate area was also searched with negative results.”

Gaetz said he was not home at the time but a family member was. The details of the Gaetz threat were first reported by Punchbowl News.

Leavitt’s statement said the threats would not slow them down. “With President Trump as our example, dangerous acts of intimidation and violence will not deter us,” she said.

The same tactics have been used in the past against some of those who’ve been viewed as Trump adversaries, including the judge who presided over his civil fraud trial in New York, the judge who presided over Trump’s federal election interference case and the prosecutor who brought that case, special counsel Jack Smith, as well as the district attorney’s office in Georgia and New York that brought criminal cases against Trump.
