A sports reporter who revealed this week that President Donald Trump called the White House a "dump" says at least "eight or nine" people heard the comment even though the president vehemently denied making the comment.

In an article published on Tuesday, Alan Shipnuck reported that Trump said that the "White House is a real dump" in a candid moment at Trump National Golf Club in Bedminster, New Jersey.

Trump fired back on Twitter, calling the report "totally untrue" and "fake news."

Shipnuck explained to the podcast on Wednesday that he was certain of his reporting.

Before publishing the article, Shipnuck said that he spoke to White House aide Hope Hicks, who demanded a retraction.

"It’s not a lie," Shipnuck recalled telling Hicks. "The president said this in front of eight or nine members and staffers at [Trump] Bedminster."

"The week of the U.S. Women’s Open [in July], I heard the same story told by two or three different other sources," he added. "This is certainly a moment that has already passed into legend at Trump Bedminster. It might be inconvenient for her boss and she might wish he didn’t say it, but it’s not a lie."
