Donald J. Trump, whose bid for the Republican presidential nomination has shaken up the race, will participate in a more common civic activity next week: jury duty.

Mr. Trump has been summoned to serve in State Supreme Court in Manhattan, and plans to report there on Monday morning, said Michael Cohen, an executive vice president at the Trump Organization and special counsel to Mr. Trump.

Despite Mr. Trump’s busy campaign schedule — he is set to appear at the Iowa State Fair on Saturday and has pledged to give fairgoers free rides on his personal helicopter from the parking lot — Mr. Cohen said that his bid for the Republican nomination would not be slowed by whatever time, if any, he might end up sitting on a jury.

“Despite the time that Mr. Trump is required to fulfill this civic obligation, the campaign will continue to go on,” Mr. Cohen said. “He is happy to comply with his civic obligation.”
