“President Trump announced today that he will consider banning the sale of all nontobacco-flavored vaping products, which is a shame, because vaping was the only way most American kids would ever find out what fruit tastes like.” — SETH MEYERS “I mean, just listen to the flavors. You’ve got mango, jelly bean, birthday cake — those are clearly for kids, right? Adults don’t flavor their drugs. Like, I watched ‘Narcos’ — there was never a moment where someone was like, ‘Let me sample your product, man. Ah, yeah, butterscotch, I like it.’” — TREVOR NOAH

During Mr. Trump’s remarks on vaping, he told reporters that the first lady, Melania, had taken an interest in the subject because “she has a son” — an odd reference to the couple’s teenage son, Barron Trump.

“Or so I hear, I’ve not seen him for a while. He better not be vaping!” — JIMMY KIMMEL (as Trump) “At least Darth Vader claimed his son. If Trump was the dark lord, he would be like, ‘Luke, she is your mother.’” — TREVOR NOAH “The first lady has got a son — together. It’s a mutual son. Of course, I’m very involved with the doings of it, and so is the first lady, who is a lovely mother, together, who I love and know her name. So well that I won’t waste your time saying it out loud.” — STEPHEN COLBERT (as Trump) “But, look, you can’t fault Trump for not being super eager to claim responsibility for his son. I mean, the dude has been burned twice.” — TREVOR NOAH

Bolton’s Bolting

Mr. Trump continued to speak about the exit of his third national security adviser, John R. Bolton, from the White House this week. On Wednesday, Mr. Trump referred to Mr. Bolton as a “tough guy; so tough, he got us into Iraq.” But he said that despite their disagreements, he wished Mr. Bolton well.
