(L/R) US Secretary of Homeland Security Markwayne Mullin looks on as President Donald Trump speaks to reporters after stepping off Air Force One at Joint Base Andrews, Maryland on May 20, 2026, as they return to Washington, DC, after President Trump gave the commmencement address to the US Coast Guard Academy's 2026 graduating class. President Trump said that it was a "very big moment" on Wednesday after the Justice Department indicted 94-year-old former Cuban president Raul Castro over the 1996 downing of civilian planes manned by critics of the communist state (also known as the "Brothers to the Rescue" murders).
