Hawaii Rep. Tulsi Gabbard, a vice chairwoman of the Democratic National Committee, said the committee disinvited her from the first Democratic presidential debate after she publicly called for more face-offs. Ms. Gabbard said her staff received the message last Tuesday from the chief of staff to Florida Rep. Debbie Wasserman Schultz, the DNC chairwoman, a day after she appeared on MSNBC demanding more than the current six sanctioned debates, The New York Times reported.
