Raw Story reports that Transportation Secretary Sean Duffy's apparent nudge to stop Homeland Security Secretary Markwayne Mullin from talking at a White House press conference fueled cover-up questions after a nationwide ground stop of flights. Mullin blamed new equipment and security patches overwhelming the older system, while Duffy faulted a contractor's botched router update and denied any cyberattack, and federal records show Air Space Intelligence, whose AI system Mullin's remarks tied to the outage, donated $12,500 to Duffy's son-in-law's campaign.
