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 spokesman for Trump’s transition team said.

The nominees and appointees “were targeted in violent, un-American threats against 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 the police claiming that a life-threatening situation is taking place. It is meant to draw SWAT teams to a location and can lead to lethal outcomes.

Three senior law enforcement officials briefed on the incident, which involved several 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 via social media, officials said. The threats did not involve US intelligence proteges such as Trump or Vice President JD Vance.

The FBI said in a statement that it is “aware of numerous bomb threats and spoofs 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 any , what they deem suspicious, to law enforcement.”

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

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

The White House said President Joe Biden had been briefed on the threats and that the administration “is in contact with federal law enforcement and the president-elect’s team and continues to monitor the situation closely. The response by federal law enforcement, along with state and local authorities, continues. The President and the administration unequivocally condemn threats of political violence.”

Among those who said they were targeted are Rep. Elise Stefanik, Trump’s nominee to be ambassador to the United Nations; former rep. Lee Zeldin, who has been nominated to lead the Environmental Protection Agency; Brooke Rollins, Trump’s pick for Department of Agriculture; and former rep. Matt Gaetz, Trump’s nominee for US attorney general, withdrew his name from consideration last week.

Stefanik’s office said in a statement that Stefanik, RN.Y., her husband and their three-year-old son were driving home from Washington “when they were informed of a bomb threat at their residence. New York State, County law enforcement, and the US Capitol Police responded immediately with the highest level of professionalism.”

Zeldin, a former New York GOP congressman, said in a statement that a “pipe bomb threat targeting me and my family at our home today was sent in with a pro-Palestinian themed message. My family and I were not home at the time and are safe. We are working with law enforcement to learn more as this situation develops.”

Rollins tweeted that “a threat was issued against our home and family. Thanks to the quick response of @fortworthpd we were unharmed and returned home quickly.”

Gaetz, R-Fla., confirmed to NBC News that he was also among the targets.

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 it was inconclusive, leading to the bomb squad being called.

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 threats and violence will not deter us,” she said.

The same tactics have been used in the past against some of those who have been viewed as Trump opponents, 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, the special counsel Jack Smith, as well as the Georgia and New York district attorney’s offices that brought criminal cases against Trump.
