Halsey jumped onto Twitter yesterday (May 27) to call out Ivanka Trump over an insensitive tweet. 

Trump had tweeted a photo of herself holding her baby with the caption: "My <3! #SundayMorning”

Halsey replied: "I wonder what #SundayMorning is like for the parents of 1500 lost children your father is responsible for. Fuck your #SundayMorning”.
