Bernie Sanders's campaign on Saturday called for the removal of two Clinton backers from crucial positions in the Democratic National Committee's convention. Calling them "aggressive attack surrogates," the Sanders camp decried the involvement of Connecticut Gov. Dannel Malloy, who is the co-chairman of the platform committee, and former Massachusetts Rep. Barney Frank, who leads the rules committee. "Governor Malloy and Mr. Frank have both been aggressive attack surrogates for the Clinton campaign," Sanders campaign counsel Brad Deutsch wrote in a letter to the DNC. "Their criticisms of Sen. Sanders have gone beyond dispassionate ideological disagreement and have exposed a deeper professional, political and personal hostility toward the senator and his campaign."
