Trump orders revival of Keystone XL and Dakota Access pipelines

Native American and climate change activists condemn president for 'pledging allegiance to oil companies and Wall Street' after signing of executive orders

Donald Trump was sharply criticised by Native Americans and climate change activists on Tuesday after he signed executive orders to allow construction of the Dakota Access and Keystone XL oil pipelines.

Both pipe projects had been blocked by Barack Obama's administration, partly because of environmental concerns. But Trump has questioned the science of climate change and campaigned on a promise to expand energy infrastructure and create jobs.
