Central Americans who traveled through Mexico arrived over the weekend in Tijuana. The caravan began its journey about four weeks ago, walking and riding buses to the U.S.-Mexico border.
Many are fleeing violence in their home countries.
The caravan received attention after President Donald Trump and members of his Cabinet called it a threat to the United States. Supporters rallied on both sides of the border Sunday, April 29, 2018, and some climbed the wall to sit or wave signs under the watchful eyes of U.S. Border Patrol agents.
