WASHINGTON — Another Trump is on her way to the capital.

Tiffany Trump, the 23-year-old daughter of President Trump and Marla Maples, the second of his three wives, plans to attend law school at Georgetown University, a school official said on Monday.

“She has taken all the steps to enroll,” said Mimi Koumanelis, a spokeswoman for the school.

Ms. Trump’s decision ended monthslong speculation about where she would choose to go to school, and on what merit. Would it be Yale, the top-ranked law school in the country, according to U.S. News and World Report? (It is unclear if she applied there.) Or would it be Harvard, Columbia or New York University, all top-flight schools where Ms. Trump was reported to have visited last fall?

In the end, it seems that Ms. Trump kept it in the family.

Eric Trump, Mr. Trump’s second son, has a degree from Georgetown, where the law school is ranked 15th, and is a member of the school’s Business, Society and Public Policy Initiative advisory board. Ivanka Trump, Mr. Trump’s elder daughter, who serves in the White House as assistant to the president, attended Georgetown for two years before transferring to the Wharton School of the University of Pennsylvania.

Ms. Trump’s appearance in Washington will most likely subject her to a newfound degree of scrutiny, one at odds with the lower profile she has kept over the years. According to reports, Ms. Trump had difficulty adjusting to life on the campaign trail with her family, and her mother suggested that her relationship with Mr. Trump had been more distant compared with those of her siblings.
