FBI Investigating Threatening Letters Containing White Powder Sent to GOP Lawmakers Across 3 States

Republican legislators in Montana, Tennessee, and Kansas have received anonymous letters containing white powder over the past week.
The FBI has begun investigating the incidents and says preliminary tests show no threat to public safety, though officials urge caution.
Around 100 such letters have been reported in Kansas, while a small number have also been received in Montana and Tennessee.
Elected officials in all three states have pledged to support law enforcement in identifying and stopping the perpetrator of these threats.
The substance contained in the letters remains unidentified, though the FBI says it does not appear to be toxic.
