More than 90 letters with ‘suspicious’ white powder sent to state officials, Kansas authorities say

The FBI and multiple state agencies are investigating after dozens of letters containing a “suspicious” white powder were sent to Kansas state legislators and public officials on Friday.

The Kansas Bureau of Investigation initially stated on Saturday that more than 80 such letters had been reported across the state, but that number increased to more than 90 by Sunday, according to a spokesperson for the bureau.

The substances tested so far have not been deemed explosive nor are they a biohazard, a source familiar with the matter told ABC News. Many of the letters were sent to Republican legislators and Kansas Attorney General Kris Kobach, the source said.
