WASHINGTON — Donald Trump hopes to bring his signature brand of glitz to the nation’s capital with a new luxury hotel in the city’s third-tallest building.

Trump plans to break ground Wednesday on a $200 million hotel that will transform the Old Post Office Building on Pennsylvania Avenue between the White House and the Capitol.

The 115-year-old building includes a 315-foot observation tower that offers panoramic views of downtown Washington. It was under-utilized in recent years, housing small vendors that catered mostly to tourists.

The new Trump International Hotel is expected to open in 2016. It will feature 270 guest rooms and two presidential suites of more than 3,000 square feet.

Trump’s daughter Ivanka and sons Donald Jr. and Eric were scheduled to join him for the groundbreaking.
