Democratic presidential hopeful Bernie Sanders, at his Friday night Millersville University rally, came out against a controversial natural gas pipeline planned to run through Lancaster County.

“I am here in Pennsylvania,” Sanders said to 3,000 supporters. “Let me just mention to you I am proud of a grassroots coalition of local residents, business owners, farmers and religious leaders in sure opposition to the Atlantic Sunrise pipeline.”

The crowd erupted in applause to the statement from the Vermont senator, who has often vocalized his stance against fracking.

“We know what we have to do and what we have to do is not build more pipelines,” he said.

Malinda Clatterbuck, a local outspoken activist against the proposed natural gas pipeline that would pass through 36.5 miles of Lancaster County, was one of the featured speakers before Sanders appeared on stage.

“We are fighting this pipeline because there’s nothing natural and there’s nothing clean about so-called natural gas. It’s just another dirty fossil fuel,” Clatterbuck, of Martic Township, said.

Clatterbuck said the pipeline would harm the environment and pollute the water supply.

She said she stands by Sanders for his opposition to corporate greed and his support of environmental standards.
