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.

With his opening rounds of memoranda and executive orders, Trump repealed dozens of former President Joe Biden’s actions, began his immigration crackdown, withdrew the U.S. from the Paris climate accords and sought to keep TikTok open in the U.S., among other actions. He pardoned hundreds of people for their roles in the Jan. 6, 2021, attack on the U.S. Capitol.

In his first address after being sworn in on Monday, President Donald Trump repeated several false and misleading statements that he made during his campaign. They included claims about immigration, the economy, electric vehicles and the Panama Canal.

Donald Trump will act swiftly after the ceremony, with executive orders already prepared for his signature to clamp down on border crossings, increase fossil fuel development and end diversity and inclusion programs across the federal government.

Pope Francis made the comments during an appearance at an evening talk show, and then followed up Monday with an official telegram of congratulations to Trump on the day of his inauguration. Francis said he prayed that America would live up to its ideals of being a “land of opportunity and welcome for all.”

Gov. J.B. Pritzker and Mayor Brandon Johnson have both said they are prepared to confront President-elect Donald Trump's policies head-on. But it is unclear how Trump will make good on his promises of retribution, and what power city and state officials will have to resist or thwart federal authorities.
