Organizers of US-bound immigrant caravan accuse Trump of 'bullying,' 'threats of mass violence'

The organization behind the 1,000-person strong caravan of Central Americans surging toward the United States' southern border accused President Trump on Monday of "bullying" immigrants and threatening "mass violence" -- while Trump again warned the advancing procession "had better be stopped." Pueblo Sin Fronteras, or People Without Borders, fired back at Trump after the president's Twitter tirade urging Congress to invoke the “nuclear option” -- requiring only a simple majority to pass legislation -- in order to pass bills for the Deferred Action for Childhood Arrivals program and tough immigration reform.
