The Radio City Rockettes will perform at the inaugural celebration of Donald J. Trump next month, a spokesman for the presidential inaugural committee said Thursday.

The spokesman, Boris Epshteyn, said in an interview on Thursday that it was not yet clear in which part of the celebration they would appear. He declined to say whether the dance troupe offered to perform.

James L. Dolan, the executive chairman of the Madison Square Garden Company, said in a statement that the Rockettes were “treasured American icons,” and noted that they had performed at the inaugurations of George W. Bush in 2001 and 2005. Radio City Music Hall and the Rockettes are among the company’s brands.
