On Tuesday, the Trump administration identified more than 440 federal properties that could be sold off, a list that included high-profile buildings like the headquarters of the F.B.I., Justice Department and the Department of Health and Human Services.

By Wednesday morning, the entire inventory had been taken down, replaced by an agency web page that said the list of properties was “coming soon.”

The General Services Administration, an agency that manages the federal real estate portfolio, had already revised the list at least once. In the hours after it was published, about 100 properties, including many in the Washington, D.C., area, were removed.

The changes stirred up confusion over the Trump administration’s plan to offload a vast amount of federal property. Officials at the General Services Administration said the “disposal” of the buildings could help save hundreds of millions of dollars and ensure that taxpayers do not have to pay for “underutilized federal office space.” But the list swiftly came under criticism by Democratic lawmakers and some former federal officials who worried about the potential impact on government services across the country.

A spokeswoman for the agency said on Wednesday that officials have received an “overwhelming amount of interest” since releasing the list, and they expect to republish it in the near future after they evaluate initial input. The spokeswoman stressed that it will be continuously reviewed and updated.

The original version of the list included offices of several cabinet-level departments and other large spaces used by the Agriculture Department and the Nuclear Regulatory Commission. Those were among the buildings removed when the list was whittled down to 320 properties. Still included for possible sale in that version: buildings used by the Centers for Medicare and Medicaid Services, as well as field offices for the Social Security Administration in areas like western Pennsylvania and Saginaw, Mich.
