Based on this it seems he should not be able to.
“The National World War II Memorial was funded almost entirely by private contributions, as specified in Public Law 103-32. The campaign received more than $197 million in cash and pledges. Support came from hundreds of thousands of individual Americans, hundreds of corporations and foundations, veterans groups, dozens of civic, fraternal and professional organizations, states and one territory, and students in 1,200 schools across the country.
Donated and pledged funds were used to cover the total project costs of approximately $182 million. These costs include site selection and design, construction and sculpture, a National Park Service maintenance fee required by the Commemorative Works Act, groundbreaking and dedication ceremonies, fund raising, and the 11-year administrative costs of the project from its inception in 1993 through completion in 2004.
Remaining funds are held on deposit with the U.S. Treasury in a National WWII Memorial Trust Fund. The funds will be used by the American Battle Monuments Commission solely to benefit the World War II Memorial.”
