"I probably have a very good relationship with Kim Jong-Un," Trump was quoted as telling The Wall Street Journal in an interview on Thursday.
But Press Secretary Sarah Sanders insisted that Trump said "I'd," not "I" as the newspaper reported.
Both The Wall Street Journal and the White House posted audio recordings of Trump's remarks on Twitter. These, while not completely clear, appeared to support Sanders' account.
Sanders had earlier tweeted a written message disputing the newspaper's article.
"President Trump said, I'D probably have a very good relationship with Kim Jong Un of North Korea. I'D -- I'D -- I'D. NOT I!" the message read, with "I'D" in red ink, under a red banner reading "FAKE NEWS."
Washington and Pyongyang are in a standoff over North Korea's missile and nuclear programs, which could be used to target the United States and its allies.
Trump has repeatedly insulted the North Korean leader, describing him as mad and a "rocket man."
In the coming week the United States and Canada are to host a meeting in Vancouver on the nuclear standoff with North Korea, bringing together friendly powers from around the world.
