Dawson was known for his threats of violence, particularly on the topic of slavery. He once "threatened to cut a colleague’s throat ‘from ear to ear.’"[2] On separate occasions, he drew a Bowie knife on and raised a cocked pistol at the anti-slavery congressman Joshua R. Giddings.[3] John Quincy Adams described him as a "drunken bully."[4]
