Trump's White House ballroom costs may rise to $600 million for taxpayers.

President Donald Trump's White House ballroom project could force taxpayers to foot an eye-popping bill.

While public announcements initially cited a $400 million budget, East Wing renovations are now projected to cost $600 million.

The Washington Post reports that taxpayers will likely pay for a portion of this construction.

In a statement from last July, the White House claimed President Trump and patriot donors committed $200 million to build the structure.

That public estimate later rose to $400 million.

However, a cost summary prepared in March by contractor Clark Construction estimated the total price at $600 million.

Trump defended the rising costs in early May, stating that deep-rooted studies revealed the final design is twice the size and of far higher quality than originally proposed.

A White House spokesperson recently insisted that patriots are funding the ballroom to the tune of approximately $400 million.

This claim ignores reports that taxpayer-funded entities, including the White House Military Office and the Secret Service, were expected to provide around $150 million.

Both agencies are bankrolled by the public.

Some GOP members attempted to include $1 billion in security funding within a $70 billion immigration enforcement bill passed earlier this month.

Congress stricken that specific provision before the Senate completed its work.

Polling data from May shows that while 60 percent of Republicans supported the project, over half of all voters opposed it.

Overall disapproval for the plan involving taxpayer money stands at 65 percent.

A district court judge previously blocked construction pending congressional approval.

An appeals court later allowed work to continue while legal arguments proceed.

A three-judge panel heard testimony from the administration and a preservationist group earlier this month but has not yet issued a ruling.

Proponents argue the ballroom is necessary for presidential security.

President Trump says renovations include bomb shelters, medical facilities, and military structures.

Following a third assassination attempt on President Trump at the White House Correspondents' Dinner in April, Republican lawmakers pushed for public funds to speed up the project.

A White House spokesperson told the Daily Mail that the East Wing Modernization Project is inextricably tied to the security of the President and the White House grounds.
