Five Black Democrats in the House of Representatives have endorsed Angela Alsobrooks in the party’s Senate primary in Maryland after her main opponent, Representative David Trone, used a racial slur in a House hearing.

The five representatives, all members of the Congressional Black Caucus, did not mention Mr. Trone’s use of the slur in their endorsements of Ms. Alsobrooks. But their support for Ms. Alsobrooks, first reported by Axios, over one of their House colleagues is notable, particularly given that the Democrats’ House leaders — Hakeem Jeffries, Katherine Clark and Pete Aguilar — have endorsed Mr. Trone.
