A lawsuit was filed after Biden signed an executive order on his first day in office terminating the Keystone XL Pipeline’s construction permit, which was initially approved by Congress and signed into law by President Donald Trump. Montana Attorney General Austin Knudsen said, “The Constitution is clear that presidents do not have the power to regulate foreign and interstate commerce or to unilaterally undo an act of Congress.” He said that fallout the from the Colonial pipeline cyberattack made it very clear that we need more energy infrastructure, not less.

Two more attorneys general have announced their respective states are joining a lawsuit against the Biden administration and its “illegal” cancellation of the Keystone XL pipeline.

“The Constitution is clear that presidents do not have the power to regulate foreign and interstate commerce or to unilaterally undo an act of Congress,” said Montana Attorney General Austin Knudsen, announcing that Alaska and Florida are joining the legal fight.

In the statement, Knudsen said U.S. consumers would benefit the most by the construction of the pipeline — and are subsequently hurt the most by its cancellation.

“The fallout from the Colonial pipeline cyberattack made it very clear that we need more energy infrastructure, not less. The Keystone XL would get more oil, including Montana oil, to American refineries to be sold to American consumers,” he said.Florida Attorney General Ashley Moody and Alaska Attorney General Treg Taylor were added to a complaint filed with the United States District Court for the Southern District of Texas on Thursday, bringing the total number of states in the lawsuit to 23.
