In a little-noted interview on the Oct. 28 episode of right-wing online video show "In The Trenches with Teddy Daniels," Arizona Republican Rep. Paul Gosar suggested that his party's gubernatorial candidate, Kari Lake, could order the state's National Guard to surround and blockade the Tohono O'odham Nation, a Native American reservation that borders Mexico, ensuring that "no one passes." Gosar also offered the notion that Lake could go to the US Supreme Court to seek state authority over the reservation.

After a US federal judge unsealed documents related to the FBI's search of former president Donald Trump's Mar-a-Lago residence in Florida, fears have grown over increased threats of violence. Magistrate Judge Bruce Reinhart unsealed the search warrant and attachments Aug. 12, following a motion from the Department of Justice (DoJ). Since unsealing the documents, Reinhart has become the target of violent and anti-Semitic threats, with his personal information, including home address, shared across Twitter and far-right platforms. Threats against Reinhart have prompted the federal judiciary to renew calls for Congress to pass legislation aimed at increasing security for judges.

The Supreme Court on July 26 reversed a lower court decision that blocked President Trump from using $2.5 billion from military accounts to build a portion of his pledged border wall. The order lifts an injunction from a federal judge in a case brought by the Sierra Club and the Southern Border Communities Coalition challenging Trump's February declaration of a national emergency to access more than $8 billion to build the wall. US District Judge Haywood Gilliam in Northern California issued the permanent injunction blocking the administration from accessing $2.5 billion in diverted military funds, finding that construction would cause "irreparable harm" to the challengers' interests at the border. The Ninth Circuit Court of Appeals earlier this month declined to lift that injunction. The Supreme Court's conservative majority found that the administration had "made a sufficient showing at this stage" that the challengers do not have standing to block the diversion of the funds.

A federal judge on May 24 blocked construction of Donald Trump's border wall, ruling that Trump cannot use a "national emergency" to take money from government agencies for the barrier. Judge Haywood Gilliam of the US District Court for Northern California ruled that the diversion of the money, largely from the US military, likely oversteps a president's statutory authority. The injunction specifically limits wall construction projects in El Paso, Tex., and Yuma, Ariz. Gilliam quoted Mick Mulvaney, the acting White House chief of staff, who said in a TV interview the wall "is going to get built, with or without Congress." The judge said presidential action "without Congress," when legislators refuse a funding request from the White House, "does not square with fundamental separation of powers principles dating back to the earliest days of our Republic."

Trump's executive order officially calling for an end to separating migrant families on the border actually contains provisions laying the groundwork for the indefinite detention of intercepted migrants. Entitled "Temporary Detention Policy for Families Entering this Country Illegally," it instructs the Secretary of Defense to provide "any existing facilities available for the housing and care of alien families" to the Department of Homeland Security—a clear reference to placing detained migrants in military bases. It also charges the Defense Department with responsibility to "construct such facilities if necessary..."

President Trump's Aug. 25 pardon of former Maricopa County sheriff Joe Arpaio is a clear signal that constitutional and human rights violations are to be rewarded, not punished, under his administration. A federal judge found Arpaio guilty of criminal contempt last month, for violating a court order in a racial profiling case and continuing his immigration patrols that discriminated against Latinos. In his announcement, Trump said that "Arpaio's life and career...exemplify selfless public service." He cited Arpaio's army time and his tenure as the Drug Enforcement Administration's Arizona chief before concluding: "In 1992, the problems facing his community pulled Arpaio out of retirement to return to law enforcement. He ran and won a campaign to become Sheriff of Maricopa County. Throughout his time as Sheriff, Arpaio continued his life's work of protecting the public from the scourges of crime and illegal immigration. Sheriff Joe Arpaio is now eighty-five years old, and after more than fifty years of admirable service to our Nation, he is worthy candidate for a Presidential pardon."

Attorney General Jeff Sessions, speaking to the Justice Department's Organized Crime Drug Enforcement Task Force (OCDETF) on April 18, pledged that the Trump administration will have "zero tolerance for gang violence" from "transnational criminal organizations"—particularly singling out MS-13, the Central American narco-network that has its roots on the streets of Los Angeles. Citing a February executive order in which President Trump directed the Justice Department "to interdict and dismantle transnational criminal organizations," Sessions promised "concrete ideas to follow through" on the directive.

After President Donald Trump's inauguration, Mexico saw a wave of angry protests against his proposed border wall, with more than 20,000 marching in Mexico City on Feb. 12, chanting "Pay for your own wall!" But now this wave of anger is crystalizing around concrete legal initiatives that could be very problematic for the White House. First, the front-runner for next year's Mexican presidential election, the left-populist Andres Manuel López Obrador, has filed a complaint with the Inter-American Commission on Human Rights against the proposed wall.
