Trump’s transition team said that “several” of the president-elect’s picks faced “threats to their lives.” Such “swatting” incidents have proven difficult to stop.

Swatting is back in the news Wednesday as multiple members after multiple members of the Trump transition and cabinet picks by the president-elect faced bomb threats and swatting incidents, three senior law enforcement officials tell NBC News.

Several of president-elect Trump's nominees for his new cabinet received "violent" threats Tuesday night and Wednesday morning, according to the FBI.
