Over 300 people demonstrated at the Denver offices of Wells Fargo to urge the banking giant to ends its financing of the Dakota Access pipeline.

The protest began at the state Capitol and grew as people marched a few blocks to the office tower. About 100 got inside the lobby and asked to meet with bank officials.

Demonstrators chanted to the beat of a drum and held signs with messages like “Resist” for about a half hour. About a dozen police officers then asked them to leave and they complied.

Glenn Morris with the American Indian Movement says the protesters accomplished their goal because officials knew they were there.

Wells Fargo has said it is one of 17 banks involved in financing the pipeline and that it’s obligated by carry out its credit agreement.
