President Joe Biden pledged an aggressive response to the cyberattack that temporarily shut down the Colonial Pipeline and warned gasoline stations on Thursday not to engage in price gouging as motorists wait for fuel to start flowing back to their communities.

“Do not, I repeat, do not try to take advantage of consumers during this time,” Biden said at the White House. “Nobody should be using this situation for financial gain. That’s what the hackers are trying to do. That’s what they’re about, not us. That’s not who we are.”

The closed pipeline — which reopened Wednesday — posed a fresh set of risks to a presidency still in its early stages. The administration knew it needed to react decisively to fix the problem and ward off Republican critics who were eager to compare Biden to Jimmy Carter, whose own presidency more than four decades ago was stung by a nationwide gas shortage.

But Biden ascended to the White House as a crisis manager and knows that the possible economic damage from spiking gas prices could also jeopardize his ambitious agenda and Democrats’ control of Congress.

The president said he expects the pipeline to resume normal operations by next week and stressed the importance of improving the durability of U.S. infrastructure as part of his $2.3 trillion jobs plan. Biden said the government would take action to stop future cyberattacks, though he declined to comment on whether Colonial had paid a ransom.

“We do not believe the Russian government was involved in this attack, but we do have strong reason to believe that the criminals who did the attack, are living in Russia,” he said. “We’re also going to pursue a measure to disrupt their ability to operate. And our Justice Department has launched a new task force, dedicated to prosecuting ransomware hackers to the full extent of the law.”

The administration had been highlighting its efforts to deliver gas to service stations in affected areas. After ransom-seeking hackers shut down the pipeline last Friday, Biden’s team understood the risk of 45% of the East Coast’s gas being unavailable as lines of autos began to snake around service stations and drivers loaded up on as much fuel as possible.

The president said Thursday the “extraordinary measures” being taken had been enough to fill the fuel tanks of 5 million vehicles in the past few days, a response to service stations in Georgia, North Carolina, South Carolina and Virginia running out of gas.

Rules were relaxed so that pipeline operators could run their systems manually, instead of relying on computers. Emergency orders lifted the highway weight restrictions and expanded the hours that fuel could be transported. The Environmental Protection Agency issued waivers on gas blends and other regulations to ease supply challenges.
