Richard Grenell, the Kennedy Center's president, called the cancellations "a form of derangement syndrome".
He said that the artists cancelling shows "were booked by the previous far left leadership".
"Their actions prove that the previous team was more concerned about booking far left political activists rather than artists willing to perform for everyone regardless of their political beliefs," he added.
