The U.S. Coast Guard is facing its largest readiness crisis since World War II. That's according to Homeland Security Secretary Kristi Noem, who promised an overhaul of the service that she called the “point of the spear” in the nation’s defense.

President Donald Trump will nominate Adm. Kevin Lunday, the acting Coast Guard commandant, to fill the vacancy.

Kristi Noem, the United States Secretary of Homeland Security, made some major announcements during her keynote speech at the 144th Commencement Exercise at the Coast Guard Academy in New London on Wednesday.
