Retired General John Kelly's remarks were a rare departure from the president on one of the core issues that defined his upstart run for the presidency.
Kelly made the comments to members of the Congressional Hispanic Caucus, the Times said.
He told the lawmakers he had persuaded Trump the wall was not necessary and that the president's opinion on the once- sacred barrier had "evolved."
The Times said that in publicly differing with Trump, Kelly appears to be saying he thinks "that it is his job to tutor a sometimes ill-informed president who has never served in public office before".
