The American Civil Liberties Union (ACLU), one of Donald Trump’s largest legal opponents during his first term, said on Tuesday that it is preparing for “the worst-case scenario” regarding immigration under the new Republican administration, which will take office on January 20.

The ACLU has strengthened its alliances with other organizations to challenge the new U.S. government’s anti-immigrant measures in court, especially in states that share a border with Mexico.

“We will be litigating as we have been since the first Trump administration, through to the Biden administration, challenging any policy that is enacted that violates the Constitution and threatens the rights and dignity of immigrants in our country,” warned Victoria López, program and strategy director for the ACLU in Arizona, during a press conference.

In this regard, Felicia Gómez, from the ACLU in the border counties of San Diego and Imperial in California, stated that the fight will also be against “the threat of further dismantling of the asylum system by the Trump administration.”

Several jackets, gloves, hats, and scarves are helping migrants on the streets of Ciudad Juárez, a border town in the state of Chihuahua, Mexico, to withstand the subzero temperatures recorded in the past days in northern Mexico.

“We wear three or four jackets to be able to walk like this, face masks, ear covers, we put on three or four sweatshirts,” said Jorge Peñalver, a 28-year-old Venezuelan, on Friday to AFP.

Northern Mexico is suffering from its second winter storm. Thermometers dropped to -3°C in Ciudad Juárez on Wednesday, where migrants are waiting to enter the United States legally.

In addition to the cold, there is the “uncertainty” ahead of the inauguration of the next U.S. president, Donald Trump, who has promised to use the military to carry out a mass deportation of migrants, added Carlos Mayorga, a pastor and volunteer with the group Ángeles Mensajeros. The organization provides clothing, food, and coffee to migrants, mostly from Venezuela and Central America, where they are “not used to” freezing temperatures.

“Thank God the people here in Ciudad Juárez see us working and give us coats,” added Peñalver, who cleans windshields and car windows.

The National Weather Service predicted that subzero temperatures will continue in northern Mexico, reaching -15°C in mountainous areas of Chihuahua and Durango states.

Former President Álvaro Uribe, one of the most popular politicians in Colombia, called on Saturday for an international military intervention in Venezuela “to oust” Nicolás Maduro from power following his controversial swearing-in for a third consecutive term on Friday.

“Let that fraud know that what we advocate for is an international military intervention with the Venezuelan army to remove the dictatorship,” said the right-wing former president from the Colombian side of the border in Cúcuta.

In front of dozens of people on the streets of the city, Uribe led his announced “protest for the freedom of Colombia and Venezuela,” in support of Edmundo González Urrutia and María Corina Machado, the leaders of the Venezuelan opposition.

“We are calling for an international intervention, preferably endorsed by the United Nations, to remove those tyrants from power and immediately call for free elections,” he insisted amid applause.
