Washington DC - President Donald Trump's White House ballroom received final planning approval on Thursday, but construction remains in limbo following a judicial order handed down earlier this week.

The National Capital Planning Commission, which has several presidential appointees on its board, greenlit plans in an 8-1 vote.

The scheme aims to construct a massive ballroom on the site of the White House's East Wing – previously best known for housing the First Lady's offices. It was demolished in October.

Planning approval does not, however, mean construction can go ahead unchecked.

On Tuesday, a federal judge ordered a halt to construction, citing a need for congressional approval. The president is "steward" of the White House, Judge Richard Leon wrote. "He is not, however, the owner!"

Will Scharf, the commission's chairman and a political ally of Trump, addressed the lawsuit before the vote, saying, "That order really does not impact our action here today.

"From my perspective, we have a project before us. We've been asked to review it, and that's really our job here today."

He noted that Judge Leon had placed a two-week delay on his stop-work order to allow the Trump Administration to appeal.

The ballroom has become a passion project for Trump during his second term, and the president often discusses the plan in public appearances, press conferences, and meetings.

He has promised to meet the costs – estimated to be upwards of $400 million – with private donations, not taxpayer money.
