The letter comes after Trump ordered the Department to “review the impacts of the water system outage” on communities, and called for an investigation into the matter.

The OSC said in the letter that the government is committed to conducting a thorough and independent investigation.

It did not specify whether the investigation would focus on the breach, but the letter said “it will be possible to identify and address any remaining operational issues.”

Trump has said that the outage affected many areas of the country, including large parts of the Midwest, the Pacific Northwest and the Northeast.

In the wake of the incident, the president has ordered federal agencies to suspend operations.

The House is scheduled to vote on an emergency funding bill on Monday.
