Nope, that's the slur his detractors wish folks would BELIEVE about him. According to the folks with whom he works at NBC, and his former Senate staffers, he is NOT lazy.
I just found this from an older article by John Fund:
“Indeed, it is his need to wake up at 5 a.m. the next morning, so he can tape three Harvey segments before returning to the “Law and Order” set for a long day of shooting, that prompts Mr. Thompson to close out our chat. “With my current schedule I might have more time to myself if I gave all this up and did start a campaign,” he says as he dons a sports coat and heads for his car.”
Yeah, that’s a lazy man, all right.
