The ballroom is only one of Trump’s controversial plans to reshape Washington’s panorama.
A federal panel gave preliminary approval on Thursday for his 250ft (76m) victory arch within the nation’s capital, at the same time as members of the general public and preservationist teams gave overwhelmingly adverse suggestions.
Still, the Commission of Fine Arts, a panel made up of Trump allies, voted to maneuver ahead with the plans, with some tweaks.
The White House unveiled the plans for the gold-accented large victory arch, dubbed the “Arc de Trump”, final week.
The large monument, if given closing approval, can be taller than the US Capitol constructing and the Lincoln Memorial, and would function a golden Lady Liberty-like statue with a torch and crown.
US taxpayers will assist fund the venture, in keeping with a publicly out there spending plan for the National Endowment for the Humanities (NEH) launched by the White House.
The NEH will dedicate $2m (£1.5m) in particular funds and $13m in matching funds to the venture, it says.
Trump has beforehand mentioned that since his ballroom venture was “fully financed”, some of the leftover cash can be used to fund the arch.
