After Sen. Bernie Sanders (I-VT) questioned Hillary Clinton’s judgment for funding her campaign with Super PAC money during Thursday’s Democratic debate, Clinton framed Sanders’ comments as an attack on President Obama.

“President Obama had a Super PAC when he ran,” Clinton pointed out. “President Obama took tens of millions from contributors, and President Obama was not at all influenced when he made the decision to pass and sign Dodd-Frank, the toughest regulations on Wall Street in many a year.”

“So this is … a phony attack that is designed to raise questions when there is no evidence or support to undergird the insinuations that he is putting forward in these attacks,” she continued.

Sanders has often gone after Clinton for taking money from large Wall Street firms during the 2016 race, arguing that the donors that fund her campaign influence her policy priorities.
