The pictures appear on the Twitter feed of Robin Bell, who has previously projected wording critical of the president onto the hotel.
He has become known as a kind of projectionist provocateur and something of a "hit-and-run editorial writer," as David Montgomery described him last year in The Washington Post.
The president, in a discussion last week on immigration policy, used "shithole" to refer to certain countries from which large-scale immigration was undesirable, according to people present at the meeting.
The Washington Post saw the posted photographs but did not actually see the words at the time they were projected. Bell said he had focused his projector onto the building for about 40 minutes. He was interviewed afterward.
