At the United Nations on Tuesday, President Trump addressed the world's assembled nations with sweeping claims about American energy, the drug trade, and diplomatic achievement — only for fact-checkers at The New York Times to find that several of those claims departed meaningfully from the record.

The gap between rhetoric and verifiable fact, when it appears at this altitude, does not stay contained — it travels, and it lingers.
