Donald Trump on Thursday announced he was replacing Kristi Noem as the homeland security secretary, capping weeks of bipartisan complaints about her leadership after immigration agents killed two US citizens and reports emerged that she was involved in a personal relationship with a top deputy.

Noem’s firing was the first major personnel shake-up of Trump’s second term. The president made it public in a post on Truth Social, in which he said Markwayne Mullin, a Republican Oklahoma senator, would take over from Noem starting on 31 March.
