Just Steal It From Other Programs

The Trump administration plans to spend at least $900 million for construction projects on the White House grounds, a significantly larger price tag than has been previously reported and one that would be covered primarily by taxpayers, according to records reviewed by The Washington Post. 

Instead of securing money directly from Congress, the records show, the administration has pieced together funding from other agencies and private donors and directed it to a little-known account that typically holds a few million dollars for routine maintenance of the executive mansion.
