Portland Police were called to a Multnomah County Democratic Party meeting on Thursday after reports of an assault.

An ongoing rift between Bernie Sanders’ supporters and Democratic Party leaders turned the meeting into a shoving match and something close to a brawl.

Collins said she is ending her active involvement in the Democratic Party as a result of the incident.

“Involvement in party politics was insightful and a valuable opportunity to provide some insider perspective,” Collins wrote. “But now I’m done.”
