Homeland Security Secretary Markwayne Mullin warned that a nationwide US flight ground stop will take time to resolve, though he emphasized that travelers remain safe.

A nationwide ground stop affecting flights across the United States will require time to fully resolve, according to Homeland Security Secretary Markwayne Mullin. Speaking at the White House on Friday, Mullin confirmed that all domestic flights have been grounded while authorities work to address the underlying issue.

While officials have not ruled out a potential cyber attack as the cause of the disruption, Mullin assured the public that travelers remain safe. However, he cautioned that normal operations will not resume immediately, stating that the situation "isn't going to just be resolved and turned around within the hour."
