Trump admin updates: White House officials hold prayer vigil for Charlie Kirk

The Department of Homeland Security announced on Monday that U.S. Immigration and Customs Enforcement (ICE) has begun an expanded immigration operation in Chicago.

The crackdown, dubbed "Midway Blitz," will "target the criminal illegal aliens who flocked to Chicago and Illinois because they knew Governor Pritzker and his sanctuary policies would protect them and allow them to roam free on American streets," according to a DHS press release.

The move comes as President Donald Trump repeatedly threatens to send troops to Chicago to take on crime.

President Donald Trump's removal of Rebecca Slaughter, a Democratic member of the Republican-majority Federal Trade Commission, is now under review by the U.S. Supreme Court.

Chief Justice John Roberts on Monday issued a temporary administrative stay of lower court orders that Slaughter should be allowed to remain on the job pending litigation over the lawfulness of her termination. The justices are considering whether to take up the case.

Slaughter contends her firing is illegal.

Congress created the five-member FTC in 1914 with members appointed to seven-year terms and removable only for cause. Trump fired Slaughter purely at his discretion, arguing the law is an unconstitutional infringement on executive authority.

A landmark high court decision from 1935 — Humphry's Executor — upheld the constitutionality of the FTC removal provision; however, many of the current justices have indicated the ruling should be overturned.

President Donald Trump on Monday repeated his desire to take federal action in Chicago.

"We'd love to go into Chicago and straighten it out," Trump said as he delivered remarks at the Museum of the Bible in Washington.

Chicago is waiting to see what action the Trump administration will take after weeks of threats from the president. The city braced over the weekend for expanded immigration enforcement, with protests throughout

Trump on Monday continued to tout the federal takeover of Washington, calling the nation's capital a "safe zone."

"We could do the same thing in Chicago, New York, Los Angeles," Trump said on Monday.

Trump reiterated his view that Chicago leaders should be requesting his administration's assistance. Local officials have said any deployment of federal agents or troops would be unnecessary and illegal, and point to statistics that show overall crime is down in the city so far this year compared to last year.

President Donald Trump announced on Monday he gave his family bible to be put on display at the Museum of the Bible.

"For thousands of years, the Bible has shaped civilization, ethics, art and literature, and it's brought hope, healing, and transformation to untold millions and millions of lives. The Bible is also an important part of the American story," Trump said.

That's why I'm delighted to announce that just moments ago, I have personally delivered the Trump family Bible given to me by my mother, I remember the time she gave it to me, but it was used in both my inaugurations ... and I guess it will now be displayed right in the heart of our nation's capital, right here. And that's an honor."

The announcement came as Trump addressed the White House Religious Liberty Commission at the museum.
