Fact check: Trump's previous misstatements on immigration, the border and the wall

NBC News has fact checked more than a dozen claims ahead of the president's Oval Office speech.


With the partial government shutdown stretching into a third week, President Donald Trump is slated to deliver a prime-time Oval Office address to the nation on Tuesday "on the humanitarian and national security crisis on our southern border."

Over his past two years in office, Trump has made a number of claims around the issue of immigration, many of them false and misleading, according to NBC News reporting. Here are some of his most significant assertions, and the facts.

Claim: Building a wall will prevent drugs from flowing into the country.

The facts: It's unlikely that a wall would stop illegal drugs from coming into the U.S., since the bulk of drugs coming across the southwest border do so through legal ports of entry, hidden in cars or tractor-trailers, according to a 2015 report by the Drug Enforcement Agency.

The Trump administration knows this. Then-Department of Homeland Security Secretary John Kelly — who went on to become White House chief of staff — said in April 2017 that illegal drug traffic "mostly comes through the ports of entry."

A wall would have no effect on those legal entryways.

Claim: Federal workers want the wall.

The facts: Not according to available public surveys.

A poll by GovExec, a publication aimed at employees of government departments and agencies, conducted December 27-28, 2018, found that only about 30 percent of federal workers support a wall. About 71 percent of them oppose the shutdown.

Claim: Much of the wall has already been built.

The facts: This is false.

The White House has not yet built any new section of border fencing or wall. Trump's administration has repaired and replaced old sections of border barrier with the same kind of fencing the president derided as a candidate as insufficient.

Claim: Former presidents told Trump they should have built a wall.

The facts: Spokespeople for the four living ex-presidents have denied this claim in the press.

Claim: Thousands of suspected terrorists have been apprehended at the southern border

The facts: This is false, according to government data.

U.S. Customs and Border Protection encountered only six immigrants at ports of entry on the U.S-Mexico border in the first half of fiscal year 2018 whose names were on a federal government list of known or suspected terrorists, according to Customs and Border Protection data provided to Congress in May 2018 and obtained by NBC News. Nearly seven times as many immigrants who were on terror watch lists were stopped on the nation's northern border with Canada.

Claim: Mexico is paying for the wall with the new trade deal.

The facts: Trade experts have told fact checkers that this isfalse, too.

There's nothing in the new trade deal that earmarks funds for the border wall; revenue raised by tariffs are federal dollars that must be appropriated by Congress.

What's more, the trade deal must still be ratified by legislators in the three countries and would not take effect until 2020 at the earliest.

Claim: Previous administrations separated families at the border, too.

The facts: This claim is misleading.

Trump and other administration officials have suggested that his policy of separating families at the border — which sparked widespread public outrage in spring 2018 — was simply a continuation of what previous administrations, including President Barack Obama's, have done. Immigration experts, advocates, and former Obama administration officials said that's wrong. There was no widespread Obama-era policy of separating parents and children

There were some cases in previous administrations where families were separated, experts told NBC News, but it was the exception, not the rule.


Claim: Trump can declare a national emergency to get wall money.

The facts: It's true that the president has the authority to declare that the country is in a state of national emergency, generally.

But when it comes to where the money for the wall comes from, it's more complicated, and any move is likely to be met by a court challenge.

Legal experts told NBC News that Trump may have a legitimate case, but it depends on the legal arguments that his administration makes and where he tries to draw those funds from.

Claim: Illegal immigration costs America hundreds of billion of dollars.

The facts: Not true, according to immigration policy experts across the political spectrum.

They told NBC News that while undocumented immigrants do incur costs at the federal and state level, they also pay taxes, and Trump is certainly wildly inflating the costs.


Claim: Existing border wall sections caused "illegal traffic" to decline.

The facts: This claim needs more context — and again, no new sections of "wall" have been built.

But Trump likes to point to data — such as the fact that illegal traffic dropped 92 percent after border fencing was constructed in San Diego in 1992 — to back up his calls for a border wall. The numbers appear to be correct, albeit cherry-picked. They also require context: Traffic dropped 92 percent there over 23 years amid a border-wide trend of fewer border crossings. What's more, he's celebrating the wins of past administrations and the kind of border fencing he's long said was not enough.

Claim: Migrants are bringing disease into the U.S.

The facts:There's no evidence of this, according to a report released last month.

A group of 24 medical experts spent two years analyzing whether migration spreads disease, as well as looking into the effects that migrants have on health in their new homelands. Their conclusion: Immigrants make up a significant portion of the health care workforce, and migration boosts economies overall.

Claim: ICE is hunting down dangerous people and MS-13 gang members.

The facts: This is partly true.


Immigration and Customs Enforcement does target undocumented immigrants deemed dangerous by law enforcement, arrest and deport them, but it's a small portion of their overall work. In fiscal year 2017, there were more than 181,000 arrests. Seventeen percent of those arrests were arrests targeting criminals, and 2.6 percent of the total were gang-related arrests. The rest were administrative arrests.

As for MS-13, there were 796 arrests related to MS-13 in fiscal year 2017.

Claim: Fake news ignores crimes committed by immigrants.

The facts: This is not true. Trump has previously distorted facts to substantiate this claim, but there is no evidence that foreign nationals or immigrants commit more crimes than native-born Americans.

Claim: "Catch and release" lets immigrants stay in the U.S. indefinitely.

The facts: This is misleading, since there is no law or hard and fast policy called "catch and release" that gives undocumented immigrants carte blanche to remain in the U.S. As NBC News has reported, the term originally became popular during the Bush administration to describe the practice of releasing immigrants from detention while they await immigration court proceedings, in part because there were not enough detention facilities to hold immigrants pending immigration court proceedings.

Immigration experts say the practice is no longer common. The White House has used the term to blast the protections afforded to children and families seeking asylum in the U.S., complaining that the government can't detain asylum seekers indefinitely.
