One of the country's largest school districts, in Florida's Palm Beach County, said in its letter to parents on Friday that local police were aware of a "video circulating on Tik Tok nationally, encouraging violence in schools."
White House press secretary Jen Psaki said in a Friday Twitter post that the White House and federal law enforcement were "closely monitoring threats of violence in schools circulating on social media," but did not specify where the threats were posted. The warnings began circulating this week as the United States was reeling from the deadliest school shooting of 2021, a Novemberat a Michigan high school that left four students dead and seven people wounded. It was the latest in a decades-long string of lethal American school shootings.
Multiple schools around the country canceled classes on Friday, though it was unclear whether the cancellations were connected to the perceived Tik Tok threats.
