U.S. President Donald Trump has officially fired Kristi Noem from her position as Secretary of Homeland Security, a decision announced over social media. This comes in the wake of growing criticisms directed at Noem's leadership, particularly regarding her management of the Immigration and Customs Enforcement (ICE) operations amid an ongoing immigration crisis. Her dismissal was formally communicated just two days following a contentious hearing in Congress, where she faced tough questions from both Republican and Democratic lawmakers.
