Entire East Wing of White House will be demolished for ballroom - as Trump urged to pause project

The entire East Wing of the White House will be demolished "within days" - much more bulldozing than initially expected for Donald Trump's new ballroom construction project.

Two Trump administration officials told Sky News' US partner NBC that the demolition is a significant expansion of the initial plans announced this summer. "It won't interfere with the current building," Mr Trump had said on 31 July.

"It'll be near it, but not touching it, and pays total respect to the existing building, which I'm the biggest fan of." But a White House official told NBC News the "entirety" of the East Wing would eventually be "modernised and rebuilt". "The scope and the size of the ballroom project have always been subject to vary as the process develops," the official added.

The East Wing was built at the beginning of the last century and was last modified in 1942. Explainer: How Trump has changed the White House while in power Construction on the ballroom - which is expected to hold up to 900 people when finished - began this week.

The National Trust for Historic Preservation, a non-profit agency created by Congress to help preserve historic buildings, warned administration officials in a letter on Tuesday that the planned ballroom "will overwhelm the White House itself". "We respectfully urge the administration and the National Park Service (stewards of the White House) to pause demolition until plans for the proposed ballroom go through the legally required public review processes," Carol Quillen, the trust's chief executive, said in a statement.

'Fake news' The White House called the uproar "manufactured outrage" by "unhinged leftists and their fake news allies" in a statement. Last week, Mr Trump said the total price would be about $250m (£187m), which would be paid for by himself and private donors will pay for.

However, on Wednesday, he said the ballroom's price is "about $300m (£225m)". The 90,000 sq ft ballroom will dwarf the White House itself - and would be able to accommodate almost five times more guests than the East Room, the largest current space in the mansion.

Mr Trump says the ballroom won't cost US taxpayers at all. Instead, "donors" would pay for it.

Comcast, the parent company of Sky News, was included on a list of top donors released last week - but it is unclear how much it or others have contributed..
