President Trump on Saturday called for the cancellation of a concert series celebrating the nation’s 250th birthday this summer, after a wave of musicians pulled out.

“Cancel it,” Mr. Trump wrote on Truth Social, adding, “We should have a giant MAKE AMERICA GREAT AGAIN RALLY, for 250, instead of having overpriced singers, who nobody wants to hear, whose music is boring, and yet who do nothing but complain.”

Freedom 250, the group that is organizing the administration’s events for the birthday celebration, announced on Wednesday that a series of nine musical acts would perform during a 16-day exposition — known as the Great American State Fair — on the National Mall beginning in late June. The exposition is part of the festivities surrounding America’s 250th birthday.

But at least five musicians have since dropped out. Some of those artists said they had not been aware that the event had been part of an initiative planned by the Trump administration for the nation’s birthday.

In an earlier post on Truth Social on Saturday, Mr. Trump had suggested that, rather than canceling the concerts, he should instead headline the event.

Calling himself “the Number One Attraction anywhere in the World” and “the man who gets much larger audiences than Elvis in his prime,” Mr. Trump wrote that he should “take the place of these highly paid, Third Rate ‘Artists.’”
