Several of President-elect Donald Trump's Cabinet picks and administration appointees were the targets of "violent" threats Tuesday night and Wednesday morning, Trump spokesperson Karoline Leavitt said in a statement Wednesday.

       "These attacks ranged from bomb threats to 'swatting,'" Leavitt said. "In response, 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."

       "This morning, Congresswoman Elise Stefanik, her husband, and their three year old son were driving home to Saratoga County from Washington for Thanksgiving 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," the statement said, before going on to thank action from law enforcement officers.

       The FBI said it was taking the threats "seriously."

       "The FBI 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 agency said in a statement.

I want to express my deep gratitude to the law-enforcement professionals who did their utmost, in both speed and expertise, to protect us — as they protect our community every single day," she said in a statement.

       Lee Zeldin, the former congressman Trump has tapped to lead the EPA, said he also was targeted Wednesday.

       “A pipe bomb threat targeting me and my family at our home today was sent in with a pro-Palestinian themed message,' he said in a statement. "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. We are thankful for the swift actions taken by local officers to keep our family, neighbors, and local community secure.”
