President Trump is preparing an executive order to ban the caravan of Central American migrants from entering the United States.

Trump's plan would block the migrants - who are still nearly a month away from reaching the border - from seeking asylum, according to Politico.

Reports that the president plans to take executive action followed a tweet in which he told the caravan to 'turnaround' because border patrol agents would bar the migrants from entering the U.S.

Thousands of migrants, including many women and young children, are seeking refuge from the violence that plagues Honduras. They are making the trek through Mexico to the United States in the caravan.

U.S. law permits foreigners who are fleeing persecution in their native countries to apply for asylum on US soil. Trump's executive order would suspend this statue for all Central Americans as a matter of 'national security'.

A DHS official who had been briefed on the potential executive order told Politico it could still be abandoned or adjusted before the administration files it.

Department of Homeland Security Department Secretary Kirstjen Nielsen said that 'everything is on the table'.

'If they come here illegally with no legitimate reason to stay, they absolutely will be apprehended and removed immediately,' she told Fox News on Thursday. 'They should be seeking refuge in Mexico. To ignore refuge and continue, in some cases, to come to the United States raises questions of what their real motives are.'

'This caravan cannot come to the United States,' she continued. 'They will not be allowed in. They will not be allowed to stay.'

Trump's prospective executive order - much like his extreme vetting directive for foreign nationals from countries associated with terrorism - would rely on the law that allows a president to suspend entry of foreigners seen as 'detrimental to the interests of the United States.'

The Supreme Court eventually upheld a version of Trump's travel ban, and DHS believes an order pertaining to the caravan would be upheld, too.

'I think the courts respected a thorough national security review that was undertaken,' one told Politico. 'Here you've got something that appears to be completely political and focused on a caravan of women and children.'

Many have accused Trump of pushing his dialogue about the caravan in recent weeks as a way to rile up his base before the upcoming midterm elections.

Trump claimed on Thursday that asylum seekers would be immediately and unequivocally denied at the border.

'To those in the Caravan, turnaround, we are not letting people into the United States illegally,' he tweeted. 'Go back to your Country and if you want, apply for citizenship like millions of others are doing!'

The tweet followed a report that the Pentagon is finalizing a deployment of 1,000 troops to assist border agents with the expected influx.

Trump has said repeatedly that he was mobilizing the military, and not the National Guard, in anticipation of the caravan, even though the deployment as he's described it would violate the Posse Comitatus Act.

Around 2,000 members of the National Guard have already been deployed to the border since April.

Many of the thousands who are in the caravan are women and young children seeking refuge from violence in Honduras. Pictured are migrants in the caravan on their way to Pijijiapan, Mexico on Thursday

The caravan still remains 1,000 miles south of the border and it is estimated it would take migrants another 25 days just to reach the US.

Trump issued his latest declaration about the caravan on Thursday afternoon just before a call with Italian Prime Minister Giuseppe Conte.

He says they spoke about the new leader's hard-line efforts to curb illegal immigration.

'I agree with their stance 100%, and the United States is likewise taking a very hard line on illegal immigration,' Trump tweeted. 'The Prime Minister is working very hard on the economy of Italy - he will be successful!'

The Italian government is looking to drive out half a million unlawful migrants.

Trump has pointed to Europe twice this week as he defended his immigration tactics, which he claims are necessary to keep criminals and 'Middle Easterners' from entering the country illegally as part of the caravan.

'For those who want and advocate for illegal immigration, just take a good look at what has happened to Europe over the last five years. A total mess! They only wish they had that decision to make over again,' he said on Wednesday.

Trump has long claimed that terrorism on the continent is directly related to the European Union's free flow of people and and furthered by policies in Germany and other nations where migrants are welcomed with open arms.

'We are a great Sovereign Nation. We have Strong Borders and will never accept people coming into our Country illegally!' he declared on Wednesday, refusing to back down.

At a rally on Wednesday evening, the president tamped down his rhetoric in response to a series of bombs that were sent to his political opponents.

But he continued to claim - with no evidence - that Democrats were encouraging the caravan and want to open the illegal immigration floodgates.

'As we speak, the Democrat Party is openly encouraging caravan after caravan of illegal aliens to violate our laws and to break into our country,' Trump said of the border 'crisis' that has consumed his attention.

Trump has made immigration his top campaign issue and deployed new rhetoric this week that there are 'tough criminal elements' in the caravan.

He also claimed there 'could very well could be' Middle Easterners mixed in with the masses in a not-so-subtle suggestion that the group seeking refuge in the United States could be a Trojan Horse.

'There's no proof of anything, there's no proof of anything but they very well could be,' Trump said, providing no evidence to back up his claims.

He also called forward Vice President Mike Pence to talk about the caravan, who made unverified allegations that the migrants were formed by leftist groups and paid for by the government of Venezuelan leader Nicolás Maduro.

President Donald Trump on Tuesday admitted he has no proof there are Middle Easterners in the caravan of migrants headed to the Unites States but said there 'could very well could be.'

'At the president's direction, I spoke to President Hernández of Honduras. He told me that the caravan that is now making its way through Mexico, headed for the southern border was organized by leftist organizations and financed by Venezuela,' Pence claimed.

Trump interrupted him to add that the Democrats were also to blame, an allegation he first made at his rally in Houston on Monday night.

'And the Democrats maybe? And the Democrats,' Trump said as some of the aides, staff, and lawmakers with him in the Oval Office for a bill signing laughed.

'Well,' Pence began but before he could finish a reporter asked Trump what proof he had Democrats were behind the mass migration.

'You know what?,' Trump responded, 'You're going to find out. And we're going to see. Maybe they made a bad mistake, too. We're going to find out about that.'

Trump also argued that based on the size of the crowd of migrants, there was a 'very good chance' some Middle Easterner people were in it.

'I think there's a very good chance, honestly, that you have people in there,' he said.

'Certainly you have people coming up through the southern border, from the Middle East and other places that are not appropriate for our country. And I'm not letting them in. They're not coming in. All right? They're not coming in. We're going to do whatever we have to.'

Trump has made the migrant caravan an election issue in the midterms

Vice President Mike Pence defended President Donald Trump's claim there are Middle Easterners in the caravan of migrants headed to the United States from Central America, saying it's 'inconceivable' there wouldn't be

Trump turned the conversation back over to Pence, who earlier in the day had defended Trump's claim there are Middle Easterners in the caravan, saying it's 'inconceivable' there wouldn't be.

Pence repeated the same inconceivable line in the Oval Office.

'The United States of America intervenes and prevents 10 terrorists or suspected terrorists from coming into our country every day,' he said.

'So it is inconceivable that there would not be individuals from the Middle East as a part of this growing caravan.'

He made a similar remark at an event held by the Washington Post earlier in the day, saying: 'It's inconceivable that there are not people of Middle Eastern descent in a crowd of more than 7,000 people advancing toward our border.'

I dare you: President Donald Trump challenged a TV reporter on Monday to take his camera crew into the migrant caravan in southern Mexico and declared that they would find drug cartel gangsters and Middle Easterners mixed in with asylum-seekers from Central America

But the statistic Pence used - claiming 10 suspects terrorists are apprehended per day - has come under doubt, with fact checkers and government reports saying that number applies to incidents at all US points of entry and not just the border with Mexico.

Pence made a similar claim in February about how many suspected terrorists were being nabbed at the US-Mexico border, which he claimed was seven per day.

The fact-checking website Politifact researched his assertion and rated it a 'Pants on Fire' - their worst rating.

'Nationally in 2017, the federal government says, Homeland Security stopped 2,554 individuals on its terrorist watch list from entering the country, which breaks out to seven people a day. Most of those individuals tried to enter by air, the government says,' the website noted.

In June, Department of Homeland Security Secretary Kirstjen Nielsen defined the 10 number even further, saying they were people blocked from entering the United States, indicating it included individuals on the no-fly list and not merely those suspected of being a terrorist.

'The result is that we are identifying and stopping terror suspects who would otherwise have gone undetected. In fact, on average, my Department now blocks 10 known or suspected terrorists a day from traveling to or attempting to enter the United States,' she said.

In a statement to The Post, Pence spokeswoman Alyssa Farah affirmed the number the vice president cited applies to all US points of entry.

'In 2017 alone the US apprehended on average between 10 suspected terrorists a day attempting to enter the country illegally. And those are just the ones that we catch. It's inconceivable that this caravan - which is being broadcast around the globe - hasn't already been infiltrated by individuals with ties to extremism,' she said.

Meanwhile, The Washington Post's fact checker found that Trump's own State Department released a report in July 2017 that said there was 'no credible information that any member of a terrorist group has traveled through Mexico to gain access to the United States.'

And still, the 10 terrorists a day stat continues to be used by the White House to back up the president's claim.

On Monday, White House press secretary Sarah Sanders was asked if President Trump had 'credible evidence' there were Middle Easterners in the caravan.

She used the 10-terrorists a day number again although - unlike Pence - seemed to apply it to all points of entry in the US.

'Absolutely and we know this is a continual problem. It's not just in this. We have 10 individuals suspected or known to be terrorists trying to enter our country every day. This is a problem the president has been talking about a long time,' she said to reporters outside the White House.

The group of migrants, which started in Honduras and has grown on its journey though Central America and into Mexico, is continuing their march with the United Nations estimating earlier this week that there are some 7,200 people in the crowd.

On Wednesday Mexican authorities said the number has dropped significantly to around 3,630 people.

A team of AP journalists traveling with the caravan for more than a week has spoken with Hondurans, Guatemalans and Salvadorans.

They have not yet met any Middle Easterners.
