Norquist, the president of the anti-tax group Americans for Tax Reform, has obtained the signatures of all but 13 Republican members of Congress on his Taxpayer Protection Pledge, which is a commitment to oppose attempts to create a net increase in federal taxes.  

“They are in a thrall, they are in submission to a man whose singular focus is to keep taxes low for the very, very, very wealthy no matter what the effect is on this nation,” continued Reid.  “They fear his political retribution.”

Reid’s frustration in part stems from an anticipated filibuster from Republicans and some Democrats on the latest installment of President Obama’s spending bill over the pay-for provision that would raise taxes on Americans earning more than $1 million annually. 

On Tuesday, Reid also attacked Republicans’ allegiance to Norquist, accusing them of acting “like puppets.”

“My Republican friends, those poor folks, are being led like puppets by Grover Norquist,” Reid said. “[H]e is their leader.”

Norquist, for his part, tweeted a response to Reid later in the day suggesting the Democratic leader read the pledge for himself.
