"Funding Sources: While initially proposed as fully privately funded using surplus funds from the White House ballroom project, federal budget documents indicate that $15 million in taxpayer funds from the National Endowment for the Humanities are slated for the project, including $2 million for special initiatives and $13 million in matching funds."

Excuse me for not getting upset about $15M from whatever the "National Endowment for the Humanities" is.
