Environmental groups sued President Trump Thursday over his decision to approve the Keystone XL pipeline, citing the president’s defeats on immigration and healthcare as reason for optimism in getting a judge to reject Trump’s pipeline decision.

“He was defeated — twice — when he tried implementing a Muslim ban; he was defeated when he tried to take healthcare away from 24 million Americans, and he will be defeated once again as he tries to force this pipeline on the people who have already seen its rejection,” said Michael Brune, executive director of the Sierra Club. “This movement has already defeated the Keystone XL pipeline, and we will do so once again.”
