Medford, MA – Rep. Ed Markey (D-Malden) today urged the four possible Republican candidates in the Massachusetts Senate special election to take the people’s pledge – an agreement to keep outside special interests and billionaires from spending millions attacking candidates.

“The silence from the potential GOP candidates on the people’s pledge is deafening and a warning that outside dollars could soon spill into this race,” said Markey. “Massachusetts does not need Karl Rove, the Koch brothers and other special interests polluting our airwaves with outside negative advertising.”
