A federal court in Washington, D.C., has extended a temporary injunction against President Trump’s effort to freeze trillions of dollars of federal spending. U.S. District Judge Loren AliKhan ruled Trump’s order appears to violate the Constitution’s separation of powers, which grants Congress the authority to tax and spend. She also cited the “catastrophic” impact the freeze would have on millions of people who receive government services, including food, home heating and medical assistance.
