TIJUANA, Mexico – Many Central American migrants camped in Tijuana after crossing Mexico in a caravan said Monday that a protest over the weekend by residents demanding they leave frightened them and left them even more anxious while they try to get into the U.S. The angry protests have been fed by concerns raised by President Donald Trump’s month-long warnings that criminals and gang members are in the group and even terrorists, though there is no evidence of that. About 500 people demonstrated in an affluent section of Tijuana on Sunday against the caravan.
