Donald Trump has just trumped himself.
The Celebrity Apprentice star made news Wednesday with his "bombshell" announcement that he'd donate $5 million to the charity of President Obama’s choice if the commander-in-chief would release his college records and applications and passport records and applications. (Trump has publicly questioned whether the president was born in the U.S.)
And now, in an appearance on CBS' Late Show With David Letterman airing Thursday night, he says he'd give even more money if the president complies.
"I assume and I hope that his records are perfect," Trump says. "He picks up $5 million for charity. $5 million. From me. Immediate. Check written. I'd even go more to be honest; there, you have a scoop," he tells Letterman.
Quipped Letterman with his arms spread wide: "Would you give him one of those giant checks?"
Asked why he made the offer, Trump replied: "Transparency. Does that make sense to anybody?" Many members of the audience applauded in response.
He added: "I hope everything's perfect. I want it to be perfect. And it very well might be."
Trump also appeared on CNN's Piers Morgan Tonight on Wednesday, where he told the host that he had received “tremendous praise for the most part" even though many people had mocked him on Twitter.
Obama himself responded to Trump's offer on Wednesday's The Tonight Show With Jay Leno, joking that Trump’s beef with him dated back to their days growing up in Kenya.
"We had constant run-ins on the soccer field," Obama told Leno. "He wasn't very good and resented it. When we finally moved to America, I thought it would be over."
