The lines are starkly drawn in Pittsburgh—and, hopefully, across the country—in the wake of the Oct. 28 synagogue massacre that left 11 dead. Today, President Trump visited the synagogue, and was joined by the Israeli ambassador Ron Dermer. This took place over the protests of Pittsburgh's Mayor Bill Peduto, who asked the White House to delay the trip in light of the sensitive situation in the city. While the rabbi at the Tree of Life Synagogue, the massacre site, welcomed Trump, many members of his own congregation clearly dissented. More than 35,000 people signed an open letter to Trump from the local chapter of the progressive Jewish group Bend the Arc, stating: "You are not welcome in Pittsburgh until you fully denounce white nationalism." Hundreds demonstrated against Trump's visit under the standard of another Jewish progressive formation, If Not Now, with banners reading "ANTI-SEMITISM = WHITE NATIONALISM" and "ANTI-SEMITISM UPHOLDS WHITE SUPREMACY."

A group of environmental advocacy organizations filed suit (PDF) against the Department of Homeland Security (DHS) on Oct. 18 over concerns that the border wall will result in detrimental environmental impacts to the areas surrounding the wall construction sites. The Secretary of Homeland Security's office has issued a series of waivers, dubbed the Lower Rio Grande Valley Border Wall Waivers, that would exempt construction projects related to the planned border wall from federal environmental regulations, including the National Environmental Policy Act, the Endangered Species Act and the National Wildlife Refuge System Administration Act. The advocacy groups argue that the broadness of the waivers would violate the Take Care Clause, the Separation of Powers Doctrine, the Non-Delegation Doctrine and the Presentment Clause of the Constitution.

In Episode 13 of the CounterVortex podcast, Bill Weinberg deconstructs Trump's executive order ostensibly ending the policy of family separation on the southern border, and demonstrates how it actually lays the groundwork for indefinite detention of migrants on military bases. The Central American peasantry, expropriated of its lands by state terror, CAFTA and narco-violence, is forced to flee north—now into the arms of Trump's new gulag. The judiciary may yet pose an obstacle to enforcement of Trump's order, but this brings us to the Supreme Court's upholding of Trump's Muslim travel ban and the grim implications of Justices Anthony Kennedy's imminent resignation. With Congressional calls mounting for putting off confirmation of Kennedy's replacement while Trump remains under investigation over the 2016 electoral irregularities, a constitutional crisis is imminent.

In what the New York Times somewhat hyperbolically calls a "clash," US Border Patrol vessels have over the past two weeks stopped at least 10 Canadian fishing boats near Machias Seal Island between Maine and New Brunswick. Canada has responded by beefing up its Coast Guard patrols in what is being termed a "disputed gray zone" between the two countries' territories. "There is no illegal immigration going on there," a bewildered Canadian fisherman told the Times. "It seems silly." Most observers see it as related to the current bitter trade dispute between Washington and Ottawa. The Canadian Broadcasting Corporation says the US Border Patrol has stopped over 20 Canadian vessels so far this year in "contested waters" in the Bay of Fundy, and "has no intention of stopping." The so-called Grey Zone consists of some 700 square kilometers of lucrative lobster waters where the Bay of Fundy meets the Gulf of Maine, although few actually live in it. Machias Seal Island is a migratory bird sanctuary maintained by the government of Canada, but is otherwise uninhabited.

Andres Manuel Lopez Obrador—known by his initials AMLO—will be Mexico's next president, following his victory in the July 1 election. By any measure, this is historic—it is the first time a candidate of the left has had his victory honored, after three tries. In 1988, Cuauhtémoc Cárdenas of the Democratic Revolutionary Party (PRD) almost certainly had his victory stolen by fraud. Then, in 2006, AMLO himself, then running with the PRD, claimed his victory was similalry stolen. His supporters launched a protest occupation of Mexico City's central plaza, the Zocalo, and there was talk of forming a "parallel government." Now AMLO, running with his new vehicle, the National Regeneration Movement (Morena), has made it. There is a sense of a real break with Mexico's traditional political parties, The once-hegemonic Institutional Revolutionary Party (PRI) is again discredited, as narco-violence only escalated under the incumbent President Enrique Peña Nieto. AMLO's old vehicle the PRD meanwhile formed an unlikely coalition with the right-wing National Action Party (PAN). 

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..."

In a press briefing on June 5, Ravina Shamdasani, representative for the UN High Commissioner for Human Rights, called on the US to halt its recently mandated practice of detaining undocumented migrants and separating them from their children. Attorney General Jeff Sessions last month announced a "zero tolerance" policy on illegal border crossings, with prosecution of all apprehended. "The practice of separating families amounts to arbitrary and unlawful interference in family life, and is a serious violation of the rights of the child," Shamdasani said. "Children should never be detained for reasons related to their own or their parents' migration status. Detention is never in the best interests of the child and always constitutes a child rights violation."

US District Judge Gonzalo Curiel in San Diego granted summary judgment (PDF) for the Trump administration Feb. 27, allowing construction of a border wall between the US and Mexico to proceed. Plaintiffs, including the Center for Biological Diversity, Defenders of Wildlife, Sierra Club, Animal Legal Defense Fund, the peole of the state of California and the California Coastal Commission had sought summary judgement and injunctive relief over waiver determinations issued by the Department of Homeland Security that regarded San Diego and El Centro as "high areas of illegal entry," both in need of replaced border fences.
