Trump 2nd term updates: Trump says USAID is run by 'radical lunatics'

President Donald Trump signed two executive orders Friday focused on emergency response, one which creates a task force to conduct a "a full-scale review" of FEMA to "recommend to the President improvements or structural changes to promote the national interest and enable national resilience."

The task force -- which is intended to be no larger than 20 people -- is expected to "meet regularly" for a year. Among the directives in the order is to evaluate "whether FEMA can serve its functions as a support agency, providing supplemental Federal assistance, to the States rather than supplanting State control of disaster relief."

They could recommend that FEMA be dismantled, but Congress would need to act in order to do away with the agency.

The second executive order, called "Emergency Measures To Provide Water Resources In California And Improve Disaster Response In Certain Areas," calls for a plan for the federal government to assert power over California's water system.

One section outlines actions for the government to go around state and federal law to more directly assert control of California's water management -- though it's not clear how much of an impact this order will have.

Arriving for his first full day at the Pentagon as defense secretary, Pete Hegseth stopped to talk to reporters to lay out some of his priorities.

"It's an honor to be here," Hegseth said after being greeted by Gen. CQ Brown Jr., chairman of the Joint Chiefs of Staff.

Hegseth said that would include removing DEI efforts inside the Pentagon, reinstating service members discharged because of COVID-19 vaccine mandates and building an Iron Dome -- though experts have said the latter may not be realistic for the U.S.

He also said the Pentagon would provide "whatever's needed" at the southern border as Trump carries out his immigration crackdown.

Hegseth previously suggested the firing of Brown as well as other senior officers who were involved either in the chaotic withdrawal of troops from Afghanistan or "woke" DEI initiatives.

Asked on Monday if he wants to fire Brown, Hegseth said: “I’m standing with him right now. Look forward to working with him."

TV show host Dr. Phil McGraw joined Tom Homan, Trump’s "border czar," and ICE officers in Chicago on Sunday for "targeted operations" to enforce immigration law.

McGraw, who filmed an arrest and posted the footage to X, claimed officials detained an alleged convicted sex offender and internet predator from Thailand.

As part of a dedicated, increased effort from U.S. Immigration and Customs Enforcement officials since President Donald Trump took office, ICE reported 956 arrests on Sunday.

ICE reported this figure, along with 554 detainees temporarily lodged with other agencies, in a post on X.

Operations spanned from Atlanta, Georgia, to Los Angeles, California — including major metropolitan areas like Chicago, Illinois, but also affecting smaller cities like Omaha, Nebraska.
