“Does anybody really believe that a reporter, who nobody ever heard of, ‘went to his mailbox’ and found my tax returns?” Trump tweeted at NBC News. "FAKE NEWS!”

The White House late Tuesday preemptively released some of Trump’s 2005 income and taxes information as MSNBC teased leaked documents on “The Rachel Maddow Show.”

Trump reported $150 million in income and paid $38 million in federal taxes in 2005, the White House said in a statement.

Johnston, who authored the recent book “The Making of Donald Trump,” suggested on MSNBC late Tuesday that it is “entirely possible” Trump is the source of the tax forms.

“Donald Trump has over the years leaked all sorts of things,” he said. "Donald has a long history of leaking material about himself when he thinks it’s in his interest.”

Citing an IRS audit, Trump last year became the first major nominee in decades not to disclose his tax returns during a presidential campaign. The IRS has said an audit does not prevent a person from releasing tax information.
