About 300 hundred protesters marched on City Hall on Tuesday evening to witness the Salt Lake City Council adopt a joint resolution with Mayor Jackie Biskupski in support of the Standing Rock Sioux Tribe's opposition to the Dakota Access Pipeline.

Protesters marched from the Bennett Federal Building down State Street to City Hall to observe the unanimous vote.

Two weeks ago, more than 100 protesters attended the City Council's evening meeting. About 50 of them spoke in favor of hundreds of protesters in North Dakota who want to stop the pipeline that's planned to cross ancestral lands.

Last month, Biskupski, along with mayors from Los Angeles; Seattle; Portland, Ore.; and Madison, Wis., sent a letter to President Barack Obama, asking him to halt construction of the pipeline until a full environmental and cultural review is completed.

"Salt Lake City is home to several Native American peoples representing the Diné, Ute, Shoshone, Paiute, Goshute and other tribes, which enhance the cultural diversity of the city," Biskupski said. "It is important for us to recognize the connection all tribes share with one another, and respect the significance all Native Americans place on ancestral territory, even when they are thousands of miles away."

Also Tuesday, demonstrators in cities across the country rallied for the Standing Rock Sioux. In San Francisco, Phoenix and Philadelphia, marchers demanded that Obama reject the Dakota Access Pipeline project before leaving office.
