Sanders said the executive actions “ignored the voices of millions.”

“Today, President Trump ignored the voices of millions and put the short-term profits of the fossil fuel industry ahead of the future of our planet,” Sanders said in a statement.

"Millions of people came together all over this country to stop the Keystone XL and Dakota Access pipelines and say we must transform our energy system away from fossil fuels to renewable energy,” Sanders said.

Sanders vowed to continue to work to stop the pipelines moving forward.

"At a time when the scientific community is virtually unanimous in telling us that climate change is real, it is caused by human activity and it is already causing devastating problems, we cannot afford to build new oil pipelines that lock us into burning fossil fuels for years to come,” Sanders said. “I will do everything I can to stop these pipelines and protect our planet for future generations."

Trump signed a pair of executive actions on Tuesday to continue construction on the pipelines. Trump said the construction projects will create “a lot of jobs.”

The Obama administration had rejected the Keystone pipeline and delayed construction on the Dakota Access pipeline.

Last year, many protested the construction of the Dakota Access pipeline for months until the project was delayed. The pipeline, located near the Standing Rock Sioux reservation in North Dakota, would have impacted cultural sites and their drinking water.
