More artists have canceled scheduled performances at the Kennedy Center following the addition of President Donald Trump’s name to the facility, with jazz supergroup The Cookers pulling out of a planned New Year’s Eve concert, and the institution’s president saying the cancellations belie the artists’ unwillingness to see their music as crossing lines of political disparity.

The fresh round of cancellations after Trump put his name on the building follows an earlier artist backlash in spring. After Trump ousted the Kennedy Center board and named himself the institution’s chairman in February, performer Issa Rae and the producers of “Hamilton” cancelled scheduled engagements while musicians Ben Folds and Renee Fleming stepped down from advisory roles.

The Cookers, a jazz supergroup performing together for nearly two decades, announced their withdrawal from “A Jazz New Year’s Eve” on their website, saying the “decision has come together very quickly” and acknowledging frustration from those who may have planned to attend.

The group didn’t mention the building’s renaming or the Trump administration but did say that, when they return to performing, they wanted to ensure that “the room is able to celebrate the full presence of the music and everyone in it,” reiterating a commitment “to playing music that reaches across divisions rather than deepening them.”
