These remarks come as the Republican camp suffered a setback in the midterms, without Mr. Trump taking political responsibility for it.
The Senator Sullivan case illustrates, in his account, a mix-up of names that he believes must be corrected by an immediate transfer of votes.
The sequence thus mixes contestation of the vote, a refusal to own the record, and the highlighting of an architectural project at the White House.
He notably mentioned the case of a namesake of Republican Senator Dan Sullivan who had run as a candidate.
Nothing in the available elements indicates that he acknowledged personal responsibility for the Republican setback.
The contrast is stark between the commitment made as early as Tuesday evening to accept the verdict of the ballot box and the return, two days later, to fraud claims.
According to these statements, Mr. Trump attributes the result to irregularities rather than to a failure of his party.
