President Trump ordered the feds to intervene and coordinate cleanup efforts in the Potomac River after a six-foot sewer pipe burst open during a cold snap last month. The pipe — which belongs to DC Water and was located in Cabin John, Md., just northwest of Washington — collapsed on Jan. 19, unleashing approximately 243 million gallons of raw sewage that had overflowed from the collapse site as of Feb. 6, per the utility.
