We are taking samples to our testing facilities. Subsequent tests have indicated it's not a nerve agent.
Test results have been cleared and all test results are negative.
At approximately 6:30 pm (2330 GMT) this evening we received an alarm at the Capitol Police for a nerve agent in the attic of the Russell building.
This is on the Senate side of the Capitol (building). At this time we have received negative results on this testing.
All the test results are actually negative, so that's very good news.
