“Most people don’t even know about it. We have 30,000 beds in Guantanamo to detain the worst criminal illegal aliens threatening the American people. This will double our capacity immediately,” President Donald Trump said from the White House.

Much of what Trump can do will boil down to money. Congress is expected to consider additional support soon. Trump may use emergency powers to tap the Defense Department, as he did for a border wall in his first term.

Despite the top cop’s attempt to reassure the tens of thousands of undocumented immigrants and their relatives who live in Chicago, Trump administration officials have repeatedly vowed to deport everyone who is in the United States without authorization.

If Mayor Brandon Johnson refuses to appear as requested, it could open a new front in the ongoing battle with the GOP-controlled U.S House and the Trump administration, which is attempting to strip self-proclaimed sanctuary cities of all federal funding.

Few details of the operation were immediately made public, including the number of arrests. But the sheer number of federal agencies involved showed President Donald Trump’s willingness to use federal law enforcement beyond the Department of Homeland Security to carry out his long-promised mass deportations.

A statement from the Secret Service said the agents were investigating a threat against an official they are charged with protecting.

Chicago’s immigrant communities are preparing for the worst amid President Donald Trump’s promises of mass deportation for undocumented immigrants.

The app is designed to provide resources and to alert relatives, lawyers and officials at the nearest consulate when someone is being detained or deported.

The temporary restraining order sought by Arizona, Illinois, Oregon and Washington was the first to get a hearing before a judge and applies nationally.

“We are not going to be intimidated by those acts of terror to radically shift our way of living,” Mayor Brandon Johnson said. “That’s what individuals who stoke fear into people want to see happen.”

In the face of a Trump administration directive to investigate state and local officials who don’t toe the line on the president’s orders on immigration, Gov. J.B. Pritzker and Chicago Mayor Brandon Johnson said they will stand up for law-abiding residents regardless of their legal status.

The campaign aims to educate residents about their rights in the event of being stopped or detained by federal agents with U.S. Immigration and Customs Enforcement, or ICE.

The memo, written by acting Deputy Attorney General Emil Bove, also instructs the Justice Department’s civil division to work with a newly formed Sanctuary Cities Enforcement Working Group to identify state and local laws and policies that “threaten to impede” the Trump administration’s immigration efforts and potentially challenge them in court.

In many districts across the country, educators have sought to reassure immigrant parents that schools are safe places for their kids, despite the president’s campaign pledge to carry out mass deportations.

Illinois is suing to block President Donald Trump’s executive order ending birthright citizenship, while state leaders brace for potential raids aimed at removing individuals in the U.S. without legal documentation.

Some of the orders revive priorities from his first administration that his predecessor had rolled back, including forcing asylum-seekers to wait in Mexico and finishing the border wall. Others launched sweeping new strategies, like an effort to end automatic citizenship for anyone born in America.
