LAWRENCE, Kan. (AP) — The Lawrence City Commission has issued letters of solidarity with Black Lives Matter and with American Indians protesting the Dakota access Pipeline after about 20 people staged a sit-in.

The Lawrence Journal-World reports that Tuesday’s protest delayed a commission meeting by about 45 minutes.

Commissioners initially said a letter would be written within 24 hours, but that offer wasn’t immediately accepted. The protesters left after the commission decided to issue an initial statement of support Tuesday night and called for a continuation of the meeting Wednesday to issue official letters.

Trinity Carpenter, with Lawrence’s Black Lives Matter chapter, said the final drafts of the letters “definitely felt well thought out.” Mayor Mike Amyx says the commission will work with people of color in the community and continue listening.
