Now, Trump has responded to the whole ordeal. Leftists were outraged that border patrol agents used tear gas on those who tried to illegally enter the U.S. Sunday, even though rocks were thrown at agents.
Take a look above.
The migrants, mainly from Honduras, are attempting to escape poverty and violence in their home country and said they would wait in Tijuana until they could request asylum in the US.
However, video of the scene also showed a cloud of tear gas that sent people running and screaming, including families with young children.
But Sunday's action affected only the San Ysidro crossing and the US forces appeared limited to Customs and Border Protection officers and Department of Homeland Security police, backed by San Diego police and the California Highway Patrol.
According to the Times, the border crossing reopened Sunday night.
A small group, some of them bearing the Honduran flag, broke off and headed a few hundred feet (metres) away toward a canal between Tijuana and San Diego that leads to the border fence.
Mexico to shore up border security, deport migrants who tried to enter U.S.
More than 5,000 Central American migrants have been camped out for more than a week at a sports complex in Tijuana awaiting an opportunity to seek asylum in the United States.
Tijuana Mayor Juan Manuel Gastelum said the throngs of migrants who have descended on his city is tantamount to a humanitarian crisis, and he declared an emergency.
"We can't have all these people here", Mujica said. "They pushed women and children up front, and then behind those women and children, they started throwing rocks, cement bricks. bottles at our Border Patrol agents", Judd said on "Outnumbered Overtime" Monday.
Trump has said the migrants should not easily enter the country and on Monday he threatened again to shut down the US-Mexico border, which stretches 3,200 km. Ted Cruz (R) for his seat in this month's midterm election, issued his rebuke the same day migrants were seen being tear-gassed by US agents in Tijuana near a port of entry.
U.S. Customs and Border Protection officers walks along a wall at the border between Mexico and the United States, as seen from San Diego on Sunday, Nov. 25, 2018. During his presidential campaign, he promised he'd have Mexico pay for a wall. It said that 1,906 of those who have returned were members of the recent caravans.
Democrats and other critics called the Trump administration's use of tear gas toward the migrants an overreaction and blamed the administration for rejecting efforts to address larger immigration issues.
