Facebook has allegedly apologized for shutting down a page to promote a protest against a caravan of migrant in San Diego.

San Diegans for Secure Borders (SDSB) founder Jeff Schwilk claimed the social network shut down his page called 'STOP the Caravan of 1500 Illegal Aliens from Mexico.'

He said Facebook took the page down on Friday night and only restored it on Saturday evening - hours after the protest was supposed to have begun.

'Our event had been up for about four weeks and had about 950 people signed up to either attend or 'interested' in attending,' Schwilk told Breitbart News Tonight.

He said he was locked out of his account for 30 days before Facebook emailed to say the event page had been restored after an 'error.'

'A member of our team accidentally removed something you posted on Facebook,' the email said.

'This was a mistake, and we sincerely apologize for the error.'

However, Schwilke conceded that the event page was only down for a few hours after a commenter said he didn't notice anything.

'Except did they actually take anything down? I didn't see anything from yesterday to today,' the commenter wrote on the SDSB page.

DailyMail.com has contacted Facebook for comment.

Although SDSB pushed for people to attend an 'informal protest' against the migrants on Sunday, it never occurred.

Earlier on Sunday, the migrants boarded five old school buses to attend a rally at a Pacific Ocean beach, with supporters gathering on both sides of the border fence and some climbing the barrier to sit or to wave signs.

Pro-caravan group Pueblo Sin Fronteras staged the demonstration in support of the asylum seekers – but urged those in attendance to avoid confronting counter-demonstrators, the San Diego Union-Tribune reports.

However, there weren't any – instead, SDSB took to Facebook to share a video of the rally from Fox News.

In a post, the group called the caravan of migrants and their supporters 'hostile foreign invaders from the south.'

It continued: 'They want our country. Now they are at the San Ysidro Port of Entry trying to push 200+ illegal aliens from the 'caravan' through on fake asylum claims.'

They urged the Department of Homeland Security to 'stop them and prosecute the foreign criminals claiming fake asylum.'

'The whole world is watching to see if we still have a country left after this radical left wing publicity stunt and border surge,' it added.

On Sunday, the group of Central Americans who journeyed in a caravan to the U.S. border resolved to turn themselves in and ask for asylum in a direct challenge to the Trump administration - only to have U.S. immigration officials announce that the San Diego crossing was already at capacity.

Nearly 200 migrants, many traveling with children, had decided to apply for protection at the nation's busiest border crossing after many fled violence in their home countries, organizers said.

The caravan got attention after President Donald Trump and members of his Cabinet called it a threat to the United States.

Shortly before the migrants were expected to arrive, U.S. Customs and Border Protection said San Diego's San Ysidro crossing would not immediately be able to handle more asylum seekers.

It can hold about 300 people at a time, and officials had been warning that it might fill up.

'At this time, we have reached capacity at the San Ysidro port of entry for CBP officers to be able to bring additional persons traveling without appropriate entry documentation into the port of entry for processing,' Commissioner Kevin McAleenan said in a statement.

'Those individuals may need to wait in Mexico as CBP officers work to process those already within our facilities.'

He said the crossing could take in additional people as space and resources become available.

Despite the announcement, about 50 people walked across a bridge and approached the port facility, but were not immediately accommodated by U.S. officials.

They were being permitted to wait in passageways until room became available, and appeared prepared to wait overnight, according to Irineo Mujica, one of the organizers of Pueblos Sin Fronteras, an organization assisting the asylum speakers.

Another 50 prepared to camp outside a gate on the Mexican side of the border crossing with backpacks and blankets hoping to get their turn on Monday.

The migrants had made their way north by foot, freight train and bus over the past month, many saying they feared for their lives in their home countries.

The Trump administration has been tracking the caravan since it started in Mexico on March 25 near the Guatemala border.

Attorney General Jeff Sessions has called the caravan 'a deliberate attempt to undermine our laws and overwhelm our system.'

Administration officials have railed against what they call America's '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, a process that can last a year.

The travelers face an uncertain future if they ask for asylum. U.S. immigration lawyers warned them that they face possible separation from their children and detention for many months.

Homeland Security Secretary Kirstjen Nielsen said asylum claims will be resolved 'efficiently and expeditiously.'

But she warned that any asylum seekers making false claims could be prosecuted, as could anyone who assists the migrants in doing so.

Administration officials and their allies claim that asylum fraud is growing and that many who seek it are coached on how to do so.
