He attended the inauguration dinner for President Buchanan at the National Hotel where he was reported to have been deliberately poisoned [1] along with many other attendees. This incident is now known as National Hotel Disease, and is believed to have been caused by food poisoning related to bad sanitation. He returned home ill, and died at Danville five weeks later.
