President Donald Trump is expected to announce on Tuesday that U.S. Space Command will move from Colorado Springs, Colorado, to Huntsville, Alabama.

The decision, confirmed by a person familiar with the matter, reverses a move by President Joe Biden in 2023, in which the Biden administration said it wanted to build a new headquarters in Colorado Springs.

Biden officials said at the time that they didn’t want to delay the command’s ability to become fully operational after a provisional headquarters was set up there four years earlier. In particular, officials said, the president didn’t want the command to be distracted with a move at a time when China was prioritizing its own military capabilities in space.

The move aligned with a recommendation by SPACECOM but was at odds with the Air Force. According to the Defense Department Inspector General and the Government Accountability Office, the Air Force recommended moving SPACECOM’s permanent headquarters to Redstone Arsenal in Alabama because it would save $426 million.

The Department of Homeland Security will be rewarding state and local law enforcement agencies that participate in immigration enforcement with "performance bonuses" for successful operations, according to the agency.

Starting on Oct. 1, law enforcement agencies participating in the 287(g) program are able to receive "monetary performance awards based on the successful location of illegal aliens provided by ICE and overall assistance to further ICE’s mission to Defend the Homeland."

Each officer on the participating task force could receive up to $1,000.

There are 40 states participating in the 287(g) program with 8,501 Trained Task Force Officers and over 2,000 additional officers in-training, according to Homeland Security.

Trump's spending bill supercharged ICE's capacity to hire and train their own officers but also get more engaged with state and local partners.

A federal appeals court is allowing the Trump administration to terminate $16 billion in grants awarded by the Biden administration to combat greenhouse gas emissions.

In a 2-1 decision, the U.S. Court of Appeals for the D.C. Circuit lifted a lower court’s order that blocked the Environmental Protection Agency (EPA) from terminating the grants.

The court concluded that a different court should have handled the claims -- the Court of Federal Claims, which handles contract disputes -- and that the Trump administration should be able to “ensure the proper oversight and management” of the multi-billion-dollar fund.

“EPA’s actions here are well within the Executive Branch’s authority and responsibility to manage the expenditure of funds and to ensure that money appropriated by Congress is properly spent for its intended purposes,” Judge Neomi Rao, a Trump appointee, wrote.

In a dissenting opinion, Judge Cornelia Pillard criticized her colleagues for passing the case to another court, writing that the move “undercuts” the ability of the court to prevent the “illegitimate seizure” of funds already awarded by Congress.

“Embracing a misguided and breathtakingly expansive conception of the Tucker Act, the majority allows the government to seize Plaintiffs’ money based on spurious and pretextual allegations and to permanently gut implementation of major congressional legislation designed to improve the infrastructure, health, and economic security of communities throughout the country,” Pillard wrote.

The Trump administration’s use of federal troops in Los Angeles to conduct law enforcement operations is unlawful, a federal judge ruled on Tuesday.

U.S. District Judge Charles Breyer issued an order prohibiting troops from engaging in security patrols, riot control, arrests, searches and crowd control. The order does not take effect until Sept 12 to allow the Trump administration to appeal.

Breyer said the use of federal troops effectively created a "national police force with the president as its chief" and violated the Posse Comitatus Act.

"The evidence at trial established that Defendants systematically used armed soldiers (whose identity was often obscured by protective armor) and military vehicles to set up protective perimeters and traffic blockades, engage in crowd control, and otherwise demonstrate a military presence in and around Los Angeles. In short, Defendants violated the Posse Comitatus Act," Breyer wrote.
