Leaders of the populist, nationalist AfD party, which entered the Bundestag for the first time after Sunday federal election, have pledged to fight an “invasion of foreigners” with its new MPs. Alexander Gauland, speaking in Berlin the morning after the election results came in, said his party would “uncompromisingly address” immigration, an issue the party has campaigned on since late 2015. “One million people – foreigners – being brought into this country are taking away a piece of this country and we as AfD don’t want that,” Gauland told a press conference late Sunday. “We say we don’t want to lose Germany to an invasion of foreigners from a different culture. Very simple.”

The University of California on Friday filed suit in federal court against the Trump administration for wrongly and unconstitutionally violating the rights of the University and its students by rescinding the Deferred Action for Childhood Arrivals (DACA) program on “nothing more than unreasoned executive whim.” UC President Janet Napolitano was secretary of DHS from 2009 to 2013, and created the DACA program in 2012.

President Donald Trump may pardon Joe Arpaio, the former Arizona sheriff who illegally used racial profiling to enforce immigration laws. It’s true, Trump has the legal power to pardon pretty much anyone. But pardoning Arpaio could send the message that state and local officials can aggressively enforce federal immigration law, even if it risks racial profiling and violating the due process rights of citizens and noncitizens.

The Israel Defense Force (IDF) has revealed the extent of the new concrete barrier currently being built around the Gaza Strip. The $836 million concrete barrier aims to eliminate the existing tunnel threat posed by Hamas, as well as any future tunnels that reach into Israel.

Searches of mobile phones, laptops, and other digital devices by federal agents at international airports and U.S. land borders are highly intrusive forays into travelers’ private information that require a warrant, the Electronic Frontier Foundation (EFF) said in a court filing Monday.

Despite being saddled with many factors associated with drug and alcohol problems, undocumented immigrants are not increasing the prevalence of drug and alcohol crimes and deaths in the United States, according to a new study. According to the study, rather than increasing substance abuse problems, a 1 percent increase in the proportion of the population that is undocumented is associated with 22 fewer drug arrests, 42 fewer drunken driving arrests and 0.64 fewer drug overdoses — all per 100,000 people. The frequency of drunken driving fatalities was unaffected by unauthorized immigration rates.

The United Kingdom has stripped more than 150 suspected jihadists and other criminals of their British citizenship in an effort to block them from returning. The government has issued what is called a “deprivation orders,” anticipating that the coming collapse of the Islamic State caliphate will leads to an influx of British Islamist militants from Syria.

The Texas Military Department has received a $2.3 million boost from the federal government to help with the state’s border-security efforts. The state’s military presence has been concentrated in the Rio Grande Valley since 2014 when a surge of undocumented migration from Central America created a crisis situation. Proponents of the move said it was needed to help an overwhelmed U.S. Border Patrol, whose agents were ill-prepared to handle the influx and concentrate on border security efforts.

Mexico’s Programa Frontera Sur (Southern Border Program or PFS) is not meeting its goals of containing the mixed migration flows from Central America to Mexico and the United States, a new study found. “Despite the fact that PFS was conceived as an instrument of state policy intended to foster development and reinforce border security while mitigating migrants’ vulnerability, the program’s results so far raise deep concerns as to whether it has complied with its stated spirit,” says one researcher.
