Kristi Noem, the US homeland security secretary, has advocated for a new travel ban on visitors from an unspecified number of countries following the shooting death in Washington DC of a national guard member by an Afghan national.
Noem posted to X her proposal on Monday night after she said she had spoken with Donald Trump, whose first-term travel ban on seven Muslim countries faced widespread criticism and followed a rocky legal path before it was eventually upheld by the supreme court.
