From the article linked in the top post:
“The final, total cost could soar into the tens of millions of dollars. The National Park Service reportedly
diverted around $2.5 million to help pay for the bash.
Shaub, who served in the government ethics role under former President
Barack Obama and then resigned after six months working under Trump, said those reported “tens of millions” were “effectively given to the Trump campaign.”
“This is what it was all about,” he added. “This and revenue for his hotel.”
Of course, that’s just an estimate. Only Team Trump could provide an accounting, and we know that Trump stonewalls on all requests for information.
