President Donald Trump appeared to change his tune Tuesday regarding federal assistance with last month's sewage spill into the Potomac River, instructing Washington, D.C., Virginia and Maryland to request the help instead of sending FEMA.

The comment comes a day after Trump said the Federal Emergency Management Agency would immediately get involved with helping to clean up the spill, which began on Jan. 19 after a sewer line breach in Maryland caused millions of gallons of sewage to be dumped into the river. 

"Maryland, Virginia, and Washington, D.C., who are responsible for the massive sewage spill in the Potomac River, must get to work, IMMEDIATELY," Trump posted on Truth Social. "If they can’t do the job, they have to call me and ask, politely, to get it fixed.

"The Federal Government is not at all involved with what has taken place, but we can fix it," he continued. "This is a radical Left-caused environmental hazard. With all of their talk about carbon footprints and everything else, they’re allowing hundreds of tons of sewage to pour into the Mighty Potomac, making it much less mighty. Act fast. I am awaiting your call."

Trump highlighted that if the government does get involved, then it comes amid the Department of Homeland Security shutdown, which operates FEMA, but that he was committed to helping fix it.

"These Democrat caused Disasters, both River and Shutdown, will only get worse," he said. "The two governors and the Mayor of D.C. must act, immediately."
