More than 5,000 Central American migrants in Tijuana, Mexico wait for their applications for asylum to be processed as Donald Trump continues to crack down on their entry into the US.
Speaking at a roundtable with supporters in Mississippi, Mr Trump claimed the tear gas used against asylum seekers was ”very safe”.
The US president went on to claim that some of the women pictured with the tear gas are not really parents but are instead “grabbers” who steal children to have a better chance of being granted asylum.

A new poll released by one of the country's largest newspapers, El Universal, stated 70 per cent of Mexicans had some sort of negative view about the migrant caravan.
Just about half supported blocking the migrants' entry into Mexico, which with this latest caravan was via a crossing point on the Suchiate River bordering Guatemala.
Around 55 per cent supported the Mexican government taking harsher measures to prevent future caravans.
Meanwhile in Mexico, support for the migrants has been declining.
With migrants feeling deflated after the tear gas clash, Mexico's National Human Rights Commission said it "reiterates that members of the caravans that cross our country should respect Mexican laws and not engage in actions that affect the communities they pass through."
"It is important to note that the fact the Mexican government protects their rights does not imply a free pass to break the law," the group said in a rare moment of less than full-throated support for the migrants.

Mr O'Rourke addressed the heart of the conflict over the weekend at the San Ysidro port of entry near San Diego, California, and Tijuana, Mexico: asylum applications.
Of the approximately 5,000 migrants camped out at a sports complex in the Mexican city, many are seeking asylum in the US as they flee rampant gang violence in their native Honduras, Guatemala, and El Salvador.
The US border agents, however, are processing less than 100 applications per day with murky timelines for those waiting.
Mr O'Rourke wrote: "Allow asylum seekers to petition for asylum at our ports of entry. They must do so peacefully and follow our laws; but we must also ensure the capacity to effectively and timely process those claims (right now 5,000 waiting in Tijuana and only 40 to 100 are processed a day)."
Beto O'Rourke may have lost his bid for the Senate seat from Texas to incumbent Republican Ted Cruz, but he has become a darling of the Democratic party in the process.
Mr O'Rourke has come out with his own response to the tensions with the migrant caravan from his perspective as a native of El Paso, Texas.
He wrote in a post on Medium: "It should tell us something about her home country that a mother is willing to travel 2,000 miles with her 4-month old son to come here. Should tell us something about our country that we only respond to this desperate need once she is at our border. So far, in this administration, that response has included taking kids from their parents, locking them up in cages, and now tear gassing them at the border."
In other Mexico-US news, the man who will head Mexico's finance ministry in December has said officials are expected to sign a revamped trade agreement with the United States and Canada at the Group of 20 (G20) summit in Argentina this week.
Carlos Urzua said late Monday that "all possibilities" point to a signing in Argentina.

Here is a wrap on the latest on the comments from the president.
Away from the border, two congressmen say a Mexican immigrant who had sought refuge in a North Carolina church has been rejected in a formal request to stay in the U.S. to support his family.
Representatives GK Butterfield and David Price have announced that Samuel Oliver-Bruno's petition for deferred deportation was denied.
Mr Oliver-Bruno, 47, was at an immigration office last week to pursue that application when he was detained. The congressmen say he left the church after 11 months because immigration officials told him to have his fingerprints taken as part of the application.

Here is Mr Trump giving his thoughts on the caravan last night:
At a roundtable in Mississippi, Mr Trump called the use of the gas "very safe" before implying that some of the pictures of mothers with children caught up in its use were actually "grabbers".
"Grabbers" are women who take children who are not their own across the border with the aim of seeking asylum.
There is no evidence this is the case.

While Mexico has called for a "full investigation" into the use of tear gas on the border on Sunday, President Donald Trump has sought to defend the use of the gas.
