WASHINGTON (AP) — The Biden administration on Thursday extended the nationwide ban on evictions for a month to help millions of tenants unable to make rent payments during the coronavirus pandemic but said this is expected to be the last time it does so.

Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, extended the evictions moratorium from June 30 until July 31. The CDC said that “this is intended to be the final extension of the moratorium.”

A Biden administration official said the last month would be used for an “all hands on deck” multi-agency campaign to prevent a massive wave of evictions. One of the reasons the moratorium was put in place was to try to prevent further spread of COVID-19 by people put out on the streets and in shelters.

As of the end of March, 6.4 million American households were behind on their rent, according to the Department of Housing and Urban Development. Nearly 1 million said eviction was very likely in two months, and 1.83 million said it was somewhat likely in the same period.
