Frontex, the European border and coast guard agency, warned that ISIS may be trying to manipulate refugees into carrying out terrorist attacks in Europe. The border agency said that its officials were also worried about ISIS sneaking in trained fighters among the mass movements of people fleeing war, hunger, and extreme poverty. Europol, the EU law enforcement agency,  noted that as of April 2016, there have been approximately 300 cases in which ISIS tried to recruit refugees entering Europe.

None of the thirty-eight Texans in Congress offered a full-throated endorsement of a complete border wall, a position popular with President-elect Donald Trump’s supporters. Instead, several members of the Texas delegation called for new policies on the border, including fencing and walls in some places, and beefing up security in other ways such as employing new surveillance technology and adding more federal agents.

No More Deaths, an immigration advocacy group, says that there is a crisis of death and disappearance happening at the U.S.–Mexico border. On Tuesday, the Tucson, Arizona-based group released Part 1 of a three-part report series aiming to bring this crisis to light. “Mass death and disappearance are the inevitable outcomes of a border enforcement plan that uses the wilderness as a weapon,” the report says.

A fundamental truth underlies the nation’s collective failure to stop illegal immigration and smuggling over the southern border: The United States demands the cheap labor and drugs. The Texas Legislature’s almost $800 million border security apparatus relies on stopping the supply of uninspected people and drugs. It’s all about boots on the ground, assets in the air, boats in the water. But addressing the country’s demand for cheap labor and drugs? Or its role in supplying the weapons drug cartels and smugglers use to protect their loads? Not so much.

Mass deportations of up to three million undocumented immigrants are expected to begin in January, when President-elect Donald Trump takes the oath of office and begins to turn his campaign promises into government policy. While Trump claims criminals are his primary target, reports suggest there aren’t enough of them to actually reach his goal. A prominent migration think tank estimates that only 820,000 undocumented immigrants have been convicted of a crime. So that means Trump would have to deport several million immigrants without criminal records to reach his goal. These people work in a range of industries, accounting for about 16 percent of those employed in agriculture, 12 percent in construction, 9 percent in hospitality, and 6 percent in manufacturing. So while kicking felons out of the country is justifiable, it seems to us that deporting the law-abiding undocumented workers who help drive our economy by undertaking jobs that Americans refuse to do is not.

A new study found that people who hold more conservative beliefs are more likely to perceive foreigners such as Syrian refugees as threatening, yet visualize them as physically smaller. Conservatives appear to imagine Syrian refugees as smaller because they believe forceful military action against terrorism will prevail. The researchers call this a “Gulliver effect,” inspired by the Jonathan Swift novel. “Comparatively, we find liberals more hesitant to endorse military action, not just from a moral perspective, but because they lack confidence that fighting will work,’” one researcher says. “Liberals in our sample tend to say that it will take years or decades for military action to be effective, if ever.” The study upheld previous research that revealed differences in how political orientation predicts the way people perceive threatening situations or individuals.

The federal E-Verify system, operated by the U.S. Citizenship and Immigration Services, screens for undocumented workers by comparing the information that job applicants submit to an employer with records maintained by the Department of Homeland Security and the Social Security Administration. A measure filed Monday in the Texas Senate would beef up punishment for employers that hire undocumented workers and seek to do business with the state.

U.S. President-elect Donald Trump has proposed deporting millions of undocumented immigrants, and many voters appear to believe that deporting illegal immigrants would boost job opportunities and wages for U.S. workers. But our economic modelling suggests different conclusions. The eight million illegal workers currently in the U.S. workforce contribute to U.S. output. If all the illegal workers left the United States, our modelling found, then the U.S. economy would be 3 percent to 6 percent smaller. A smaller U.S. economy would need fewer workers in all occupations. The exception is farm laborers and construction workers: there would be fewer jobs overall in these occupations, but there would be more jobs for legal U.S. residents. This is because deporting illegal workers would open up vacancies. Moreover, in general terms, eliminating illegal workers from the U.S. workforce would change the structure of employment for legal workers away from skilled occupations towards low-skilled, low-wage occupations.

Amid talk that the incoming administration could make good on a campaign promise to end Deferred Action for Childhood Arrivals, or DACA, the Center for American Progress estimates that ending DACA would wipe away at least $433.4 billion from the U.S. gross domestic product, or GDP, cumulatively over a decade.
