The FBI confirms that the threats are being investigated and says that bomb threats have occurred several times. Among the threats, so-called swatting has occurred, which means that a false threat has been reported to the police, who then go to a designated location – often where the targeted person lives.
The police do not go into detail about how the threats were made or who was targeted.
One of those targeted by the threats is Elise Stefanik in New York, nominated by Trump to become a UN ambassador. She received the threat, according to her own account, when she and her family were driving from Washington DC to New York.
The media company CBS reports that Trump's nomination for the post of trade minister, Howard Lutnick, was also threatened.
Lee Zeldin, nominated to lead the US Environmental Protection Agency, says he was bomb-threatened. The threat was delivered to his home.
My family and I were not at home at the time. We are grateful for the police's immediate action, says Zeldin.
President Joe Biden has been informed about the threats, according to the White House.
"The White House is in contact with federal police and the incoming president's team and continues to closely follow the situation," says a spokesperson in a statement.
"The President and administration strongly condemn threats of political violence."
Karoline Leavitt, spokesperson for Trump's organization preparing for the transfer of power, says that the police have taken strong action on the threats.
Intimidation tactics cannot deter us, our President Trump is an example of that, says Leavitt.
