NBCUniversal Inc. is feeling the heat from congressional Democrats after comedian Julia Louis-Dreyfus’s on-air use of an electronic cigarette during the Golden Globe Awards on Sunday left them fuming.

Sens. Dick Durbin of Illinois, Richard Blumenthal of Connecticut, Sherrod Brown of Ohio and Ed Markey of Massachusetts, as well as Reps. Henry Waxman of California and Frank Pallone Jr. of New Jersey, this week chastised NBCUniversal for broadcasting the “Veep” star’s e-cigarette puffing.
