President Donald Trump, in a series of tweets on Monday, claimed he would declare a "national emergency" over an issue that has frequently piqued his attention -- migrant caravans moving toward the United States through Central America and Mexico.
His tweets come just weeks ahead of the 2018 midterm elections and he has emphasized immigration as a key issue, without evidence accusing Democrats of pushing for overrun borders in what appears to be a naked fear campaign aimed at turning out his supporters. Immigration was a key issue in the 2016 presidential race.
Crowds of migrants, estimated to be about 7,200 people on Monday, resumed their long journey north on Sunday into Mexico as part of a migrant caravan originating in Central America.
Currently migrants are at the Central Park Miguel Hidalgo in the center of Tapachula. Organizers plan for them to begin moving north, reaching the northern city of Huixtla, which is about 20 miles north, and resting there.
The President, in his tweets, also made several questionable claims concerning immigration and the caravan. Among them: that "unknown Middle Easterners" are "mixed" in with the caravan, that he would be cutting off foreign aid over the caravan, and that Mexican authorities failed to stop migrants from coming into Mexico.
Asked later Monday about his assertion about "unknown Middle Easterners" in the caravan, Trump said: "Unfortunately, they have a lot of everybody in that group."
"We've gotta stop them at the border and, unfortunately, you look at the countries, they have not done their job," he said. "They have not done their job. Guatemala, Honduras, El Salvador -- they're paid a lot of money, every year we give them foreign aid and they did nothing for us, nothing."
Here's what we know:
Are there "unknown Middle Easterners" "mixed" into the migrant caravan?
Trump tweeted "criminals and unknown Middle Easterners are mixed" into the migrant caravan moving toward the United States. He called this a "national emergy" (sic).
It's unclear what "unknown Middle Easterners" Trump appears to be referring to in his tweet, since there have been no reports, in the press or publicly from intelligence agencies, to suggest there are "Middle Easterners" embedded in the caravan.
A senior counterterrorism official told CNN's Jessica Schneider that "while we acknowledge there are vulnerabilities at both our northern and southern border, we do not see any evidence that ISIS or other Sunni terrorist groups are trying to infiltrate the southern US border."
However, earlier this month, Guatemalan President Jimmy Morales claimed foreign individuals linked to terrorism were captured in the country during his administration, which began in January 2016.
"We have arrested almost 100 people highly linked to terrorist groups, specifically ISIS. We have not only detained them in our territory, they have also been deported to their countries of origin. All of you here have information to that effect," Morales said during a Conference on Prosperity and Security in Central America event attended by Secretary of State Mike Pompeo.
There's no direct link or correlation between Morales' statement and Trump's assertion on Twitter.
The Department of Homeland Security did not provide any evidence to bolster the President's claim about "unknown Middle Easterns" in the caravan when asked for it by CNN on Monday.
A department official told CNN that in fiscal year 2018, Customs and Border Protection "apprehended 17,256 criminals, 1,019 gang members, and 3,028 special interest aliens from countries such as Bangladesh, Pakistan, Nigeria and Somalia. Additionally, (Customs and Border Protection) prevented 10 known or suspected terrorists from traveling to or entering the United States every day in fiscal year 2017."
The Department of Homeland Security did not specify any Middle Eastern countries.
Pressed about the President's assertion that there are "unknown Middle Easterners" mixed in with the caravan, a State Department spokesperson said they understand there are several nationalities in the caravan and referred us to Department of Homeland Security for more information.
Will the administration cut off foreign aid? Can they?
Trump tweeted that because "Guatemala, Honduras and El Salvador were not able to do the job of stopping people from leaving their country and coming illegally to the U.S.," the United States "will now begin cutting off, or substantially reducing, the massive foreign aid routinely given to them."
It's unclear where the administration will propose to make the cuts the President appears to be talking about, and CNN has reached out to the White House and the DHS for further information.
However, the Congressional Budget and Impoundment Control Act prohibits the President from withholding -- or impounding -- money appropriated by Congress.
New York Rep. Eliot Engel, the top Democrat on the House Committee on Foreign Affairs, said Monday that his office has reached out to the Government Accountability Office to ensure that the President does not violated the act.
"Fortunately, Congress -- not the President -- has the power of the purse, and my colleagues and I will not stand idly by as this Administration ignores congressional intent," Engel said in a statement.
Under the Trump administration, and with the approval of the Republican-controlled Congress, there have already been significant cuts to foreign aid to Guatemala, El Salvador and Honduras -- the three countries he mentioned Monday -- and the administration plans to continue making cuts in fiscal year 2019.
Were authorities from Mexico unable to stop the migrant caravan from heading into the US?
Trump tweeted Monday that "Mexico's Police and Military are unable to stop the Caravan heading to the Southern Border of the United States."
There are some 7,500 people marching north as part of a migrant caravan through Mexico, caravan organizer Dennis Omar Contreras told CNN. He said the organizers did a count of participants Monday morning.
He said the migrants will leave Mexico's Tapachula for the town of Huixtla, which is located more than 20 miles northwest of their Monday morning location.
While Mexican authorities said before the caravan's arrival that anyone who entered the country "in an irregular manner" could be subject to apprehension and deportation, many migrants from the caravan appear to have circumvented authorities.
CNN crews witnessed migrants jumping off a bridge at the Mexico-Guatemala border and riding rafts to reach Mexican soil.
Mexican authorities say more than 1,000 Central American migrants officially applied for refugee status in Mexico over the past three days.
It's unclear how authorities will respond to the thousands of other migrants who are marching north.
