President Joe Biden contends the ransomware cyberattack that shut down a major U.S. pipeline is another reason Congress should pass his $2.25 trillion infrastructure spending package, saying the Russian government bears some responsibility for the hack even though there is “no evidence” of direct Kremlin involvement.

Biden’s Department of Energy is working with the management of Colonial Pipeline, the operator of one of the country’s largest fuel pipelines, after it went offline last week. Company officials decided to go offline on Friday after the Russian cybercriminal group known as DarkSide compromised the pipeline’s information technology systems using ransomware.
