White House Chief of Staff John Kelly has reportedly told Democratic lawmakers President Trump’s campaign promises to build a wall with Mexico and make Mexico pay for it were “uninformed,” The Washington Post reports. Trump’s repeated promises to “build the wall” were a regular feature of his presidential campaign. He tweeted about the necessity for a “great wall” as recently as Tuesday—suggesting his ideas about the wall may still be at odds with those of his chief of staff. In comments with members of the Hispanic Caucus on Wednesday, however, Kelly said he’d “tempered” Trump on the issue of the wall by educating him on the realities of such policies. Kelly later stood by his comments in an interview with Fox News but gave the president credit for having “evolved in the way he looks at things.” “Campaign to governing are two different things, and this president has been very flexible in terms of what’s in the realm of the possible,” he said.
