President Donald Trump is criticizing musician John Legend for not playing a role in passing criminal justice reform following a TV special on the subject in which the star appeared.
Trump also says he hasn't gotten enough credit for signing a law instituting some reforms. The law reduced mandatory minimum sentences, among other measures.
In a series of tweets late Sunday and early Monday, Trump called Legend "boring." He also said Legend's wife model Chrissy Teigen was "filthy mouthed."
Legend responded by saying Trump is hungry for praise and asked Trump's wife Melania to step in.
Teigen wrote she didn't appear on the special and used crude language to describe Trump.
