WASHINGTON — In his prime-time speech to the nation, President Donald Trump declared a border crisis that’s in sharp dispute, wrongly accused Democrats of refusing to pay for border security and ignored the reality of how drugs come into the country as he pitched his wall as a solution to varied ills.

A look at his Oval Office remarks Tuesday night:

Drugs

TRUMP: “Our southern border is a pipeline for vast quantities of illegal drugs, including meth, heroin, cocaine and fentanyl. Every week, 300 of our citizens are killed by heroin alone, 90 percent of which floods across from our southern border.”

THE FACTS: A wall can’t do much about that when drug trafficking is concentrated at land ports of entry, not remote stretches of the border.

The Drug Enforcement Administration says “only a small percentage” of heroin seized by U.S. authorities comes across on territory between ports of entry. The same is true of drugs generally.

In a 2018 report , the agency said the most common trafficking technique by transnational criminal organizations is to hide drugs in passenger vehicles or tractor-trailers as they drive into the U.S. though entry ports, where they are stopped and subject to inspection. They also employ buses, cargo trains and tunnels, the report says, citing other smuggling methods that also would not be choked off by a border wall.

Trump recently denied that traffickers use entry ports at the southern border, contradicting the evidence and assertions of his drug enforcement personnel.

Trump stretched credulity even more by comparing the wall money he wants from Congress to the cost of the entire drug problem in the U.S.: “The border wall would very quickly pay for itself. The cost of illegal drugs exceeds $500 billion a year, vastly more than the $5.7 billion we have requested from Congress.”

Wall money

TRUMP: “Democrats will not fund border security.”

THE FACTS:  That’s not true. They just won’t fund it the way he wants. They have refused his demand for $5.7 billion to build part of a steel wall across the U.S.-Mexico border

Democrats passed legislation the day they took control of the House that offered $1.3 billion for border security, including physical barriers and technology along the U.S. southern border.

Senate Democrats have approved similar funding year after year.

Democrats have also supported broader fence-building as part of deals that also had a path to legal status for millions of immigrants living in the country illegally.

In 2013, Senate Democrats voted for a failed immigration bill that provided roughly $46 billion for a number of border security measures — including new fencing — but that legislation would have created a pathway to citizenship for some of the estimated 11 million immigrants living in the U.S. illegally.

The 2013 Border Security, Economic Opportunity and Immigration Modernization Act had money to double the number of miles of fencing, to 700 miles (1,126 km), as well as for more border patrol agents. It also had a mandatory employment verification system to ensure all U.S. employees are authorized to work in the country. In exchange, however, the bill allowed immigrants living in the country illegally to apply for a provisional legal status if they paid a $500 fine and had no felony convictions.

As well many Democrats voted for the Secure Fence Act of 2006, which has resulted in the construction of about 650 miles (1,050 kilometers) of border barrier. But that legislation didn’t authorize the kind of wall Trump has long been advocating since he launched his campaign.

The Dems

HOUSE SPEAKER NANCY PELOSI: “The fact is: President Trump has chosen to hold hostage critical services for the health, safety and well-being of the American people and withhold the paychecks of 800,000 innocent workers across the nation – many of them veterans.” — response to Trump’s remarks.

SEN. CHUCK SCHUMER, Senate Democratic leader: “The president of the United States — having failed to get Mexico to pay for his ineffective, unnecessary border wall, and unable to convince the Congress or the American people to foot the bill — has shut down the government.” — response to Trump.

THE FACTS: That’s one way to look at it. But it takes two sides to shut down the government. Trump’s demand for $5.7 billion for his border wall is one reason for the budget impasse. The refusal of Democrats to approve the money is another.

Violence

TRUMP: “Over the years thousands of Americans have been brutally killed by those who illegally entered our country and thousands more lives will be lost if we don’t act right now.”

THE FACTS: His statement that people in the country illegally are a special menace to public safety is at odds with plentiful research.

Multiple studies from social scientists and the libertarian think tank Cato Institute have found that people here illegally are less likely to commit crime than U.S. citizens, and legal immigrants are even less likely to do so.

A March study by the journal Criminology found “undocumented immigration does not increase violence.”

The study, which looked at the years 1990 through 2014, said states with bigger shares of such people have lower crime rates.

As well, a study in 2017 by Robert Adelman, a sociology professor at University of Buffalo, analyzed 40 years of crime data in 200 metropolitan areas and found that immigrants helped lower crime.
