Michael Flynn, a Trump Ally, Sponsors Beethoven at the Kennedy Center

The list of donors to the National Symphony Orchestra, one of the Kennedy Center’s flagship ensembles, is usually filled with financiers, socialites, corporations and foundations.

But the name of a sponsor of this week’s performances of Beethoven’s “Missa Solemnis” stood out. It was Michael T. Flynn, the general and former national security adviser during President Trump’s first term. He was listed, along with his nonprofit, America’s Future Inc., as “performance sponsors” for the National Symphony Orchestra’s concerts from May 15 to 17.

Mr. Flynn said on social media that his nonprofit was “thrilled to sponsor a spectacular three-night performance at the John F. Kennedy Center for the Performing Arts!”

“This performance is filled with a vibrant celebration of music, culture, and the unyielding spirit uniting all Americans,” he wrote in a post on X. “The Kennedy Center shines as a proud symbol of our nation’s legacy!”

Mr. Flynn’s gift to the National Symphony Orchestra totaled $300,000, according to two people familiar with the donation who were granted anonymity because details of the gift were not publicized.

Officials at the Kennedy Center said they did not have details of the gift.

“We didn’t know how much but we welcome all sponsorships,” the center said in a statement.
