A social media account for U.S. Secretary of the Navy John Phelan, whom President Donald Trump tapped for the role despite him having zero military experience, posted the wrong date of the attack on Pearl Harbor twice late last week.

The two posts, which have since been deleted, went up Friday after Phelan ― a wealthy investor, prominent art collector and Trump campaign donor ― visited the Pearl Harbor Naval Shipyard and USS Arizona Memorial in Hawaii, saying he was “there to honor the thousands of service members and civilians who died at Pearl Harbor on June 7, 1941.” In another post, the account referred to it as “the fateful day of June 7, 1941.”

The Japanese military’s attack on Pearl Harbor, which President Franklin Roosevelt famously referred to as “a day that will live in infamy,” happened on Dec. 7, 1941. As the impetus for the United States’ entrance into World War II, it’s remembered as a day that changed the course of world history.

Newly hired Navy spokesperson Kristina Wong, a former Breitbart News correspondent, took the blame for the mistake on Monday.

“I sincerely regret the error. As the daughter of an Air Force veteran it pains me to have made this mistake,” she wrote on social media.

Veterans came out in large support for Trump in last year’s election, with about 65% of them saying they voted for him, exit polls showed. That came after he made big promises to service members and veterans during his campaign last year, vowing to raise military pay and root out its “woke” leaders.

But an internal memo obtained by The Associated Press last month found that Trump’s so-called Department of Government Efficiency, helmed by billionaire Elon Musk, plans to cut more than 80,000 jobs from the Department of Veterans Affairs, which provides health care and other services to America’s millions of veterans. The cuts will reportedly happen this summer as the department undergoes a major reorganization in August.
