Additional migrants were allowed entry into the United States for processing Tuesday, two days after a caravan of nearly 200 reached the San Ysidro Port of Entry to ask the U.S. for asylum.
As of 4:20 p.m., 28 migrants have been allowed to enter the U.S. -- eight on Monday and the rest Tuesday afternoon, according to organizers behind a monthlong caravan through Mexico.
The group was detained and will be vetted for possible asylum, while another almost 150 migrants waited on the Mexico side of the border to turn themselves in.
The migrants' journey across Mexico came under the Trump administration's watchful eye. The asylum seekers, many fleeing threats of violence from gangs in their home countries, faced an unexpected twist Sunday when U.S. Customs and Border Protection Commissioner Kevin McAleenan said San Diego's San Ysidro border crossing facility had "reached capacity."
U.S. Customs and Border Protection said Sunday afternoon that the border facility did not have enough space to accommodate them, and said in a statement on Monday that it had no estimate when the location would accept new asylum application cases.
About 50 people, many of them women and children, camped overnight on blankets and backpacks in Tijuana outside the Mexican entrance to the border crossing. The crowd grew Monday, assembled behind metal gates that Mexican authorities erected to avoid impeding the flow of others going to the United States for work, school and recreation.
Another 50 asylum seekers were allowed past a gate controlled by Mexican officials Sunday to cross a long bridge but were stopped at the entrance to the U.S. inspection facility at the other end. They waited outside the building, technically on Mexican soil, without word of when U.S. officials would let them try to claim asylum.
Irineo Mujica, a caravan organizer, said asylum-seekers who crossed the bridge remained in a waiting area on Mexican soil Monday. He alleged that U.S. authorities were refusing entry in an effort to dissuade people from trying.
"When they say they reached capacity, it's just nonsense from (U.S. authorities) so they can abandon, not attend to, and evade their responsibilities in asylum cases," said Mujica, of the advocacy group Pueblos Sin Fronteras.
Customs and Border Protection said Sunday that it will resume asylum processing at the San Diego crossing when it has more space and resources.
The San Ysidro border inspection facility that divides San Diego from Tijuana can hold about 300 people, meaning the bottleneck may be short-lived. The agency processed about 8,000 asylum cases from October through February at the crossing, or about 50 a day.
Asylum-seekers are typically held up to three days at the border and then turned over to U.S. Immigration and Customs Enforcement. If they pass an asylum officer's initial screening, they may be detained or released into the U.S. with ankle monitors.
Thousands of Haitians seeking to turn themselves in at the San Diego crossing overwhelmed U.S. border inspectors at the San Diego crossing in 2016, leading to the creation of a ticketing system for them. At one point, Haitians had to wait in Tijuana for more than five weeks for their turn.
President Donald Trump has repeatedly criticized the caravan since it started in Mexico on March 25 near the Guatemala border and headed north to Tijuana, telling campaign supporters in an email last week that it had to be stopped.
His broadsides came as his administration vowed to end what officials call "legal loopholes" and "catch-and-release" policies that allow people requesting asylum to be released from custody into the U.S. while their claims make their way through the courts, which can take years.
"Catch and release is ridiculous," Trump said Monday at a news conference with Nigerian President Muhammadu Buhari at the White House. "If they touch our property, if they touch our country, essentially you catch them and you release them into our country. That's not acceptable to anybody."
Attorney General Jeff Sessions has called the caravan "a deliberate attempt to undermine our laws and overwhelm our system." Homeland Security Secretary Kirstjen Nielsen said asylum claims will be resolved "efficiently and expeditiously" and warned that anyone making false claims could be prosecuted and said asylum seekers should seek protection in the first safe country they reach, including Mexico.
Asylum seekers did not appear to be thrown off by the delay.
Elin Orellana, a 23-year-old pregnant woman from El Salvador, said she is fleeing the MS-13 street gang, a favorite target of both Sessions and Trump because of their brutal killings committed in the United States.
She said her older sister had been killed by the gang in El Salvador, so she is attempting to join other family members in the Kansas City area.
"Fighting on is worth it," she said Sunday as she camped outside the Mexican entry to the border crossing.
