Trump-backed Potomac sewage cleanup complete after massive spill ahead of summer America250 celebrations

"Emergency repairs to the Potomac Interceptor are complete," DC Water said Saturday. "Full flow has been restored and the C&O Canal has been fully drained as part of site restoration. Since Jan 19, crews worked around the clock to stabilize the site and protect the Potomac River."

"We've been doing essentially the federal government's job because it's the federal government's job to be able to protect the Potomac interconnector because that's federal land," Moore said. "For the president now to come and attack me on this, I find that to be ... absurd."

The plaintiff, Nicholas Lailas, who is a recreational boater, is seeking compensation for people "whose property interests in and use and enjoyment of the Potomac River ... have been impaired by Defendant's conduct," the lawsuit said.

He is seeking unspecified damages.
