Dozens of Central Americans seeking asylum in the United States woke on the ground outside a California border crossing after US officials said they did not have enough space to accommodate the group engaged in a high-profile test of Trump Administration policies.
The arrival of the 220 asylum seekers has set up a showdown between migrants, citing their right to seek shelter from persecution, and the Trump Administration, which is trying to crack down on illegal immigration and says many asylum claims are fraudulent.
Trump tweeted last week that he had ordered the secretary of homeland security "not to let these large Caravans of people into our Country," adding, "It is a disgrace."
But under international law, the US Government is obliged to allow foreigners to apply for asylum.
Trump Administration officials said they will begin processing the migrants when they have the capacity, but they have not indicated when that will happen.
