NEW YORK (Reuters) - Liberal grassroots groups on Thursday launched a bid to calm tensions between supporters of the two progressive standard-bearers in the Democratic presidential race, U.S. Senators Bernie Sanders and Elizabeth Warren, who have engaged in a days-long feud after months of non-aggression.
Led by the political action committee Democracy for America, the 18 groups announced the "Progressives Unite 2020" campaign, which includes a promise to "focus our fight for the nomination against candidates supported by the corporate wing, instead of fighting each other."
