That might not play well with U.S. officials: White House press secretary Sarah Huckabee Sanders on Wednesday specifically praised Mexico for stopping the migrants from getting rides."Mexico has stepped up in an unprecedented way," Sanders told Fox News. "They have helped stop a lot of the transportation means of these individuals in these caravans, forcing them walking. They have helped us in new ways to slow this down, to break this up and keep it from moving as aggressively toward the United States."
Mexico is stopping transportation for migrants because Mexico doesn't want the United States to build a wall on the southern border.
