The Kansas governor's office was among government offices in nine states intercepting envelopes with a powdery substance.
Capitol Police closed off the reception area while they investigated. The private office was not locked down, so the governor could come and go as she pleased.
Initial tests show the substance received in Kansas was not hazardous. Tests in Florida, Georgia, North Dakota and Utah showed the same. Virgin Islands officials determined the powder there was corn starch.
Tests were pending in the other states.
Thursday's envelopes containing suspicious powder bring the total received in state capitals this week to 20, plus the Virgin Islands.
Officials in some of those states say the powder was flour, corn
starch or some other harmless food substance.
