A months-long investigation by The Washington Post has not been able to verify many of Trump’s boasts about his philanthropy.

Instead, throughout his life in the spotlight, whether as a businessman, television star or presidential candidate, The Post found that Trump had sought credit for charity he had not given — or claimed other people’s giving as his own.

It is impossible to know for certain what Trump has given to charity, because he has declined to release his tax returns. In all, The Post was able to identify $7.8 million in charitable giving from Trump’s own pocket since the early 1980s.

In public appearances, Trump often made it appear that he gave far more.

Trump promised to give away the proceeds of “Trump University.” He promised to donate the salary he earned from “The Apprentice.” He promised to give personal donations to the charities chosen by contestants on “Celebrity Apprentice.” He promised to donate $250,000 to a charity helping Israeli soldiers and veterans.

Together, those pledges would have increased Trump’s lifetime giving by millions of dollars. But the Post has been unable to verify that he followed through on any of them.

Instead, The Post found that his personal giving has almost disappeared entirely in recent years.
