AINews Summary

National DHS news dominated: President Trump removed Kristi Noem after controversy over a $220 million border-security ad campaign, and Sen. Markwayne Mullin is expected to be confirmed to replace her. The contracting process is under scrutiny, including a company incorporated in Delaware shortly before winning a $143 million contract. Separately, DHS says ICE agents will not be posted at polling sites amid Democratic efforts to bar federal agents from polling places. This batch is mostly national/DHS-focused and doesn’t directly change the Delaware GOP Senate nomination outlook, so market impact is likely limited. The Delaware-linked contracting story could add some uncertainty, but any effect on this nominee market is unclear.
