Facebook closed the "war room" it built ahead of U.S. midterm and Brazil elections, a spokesperson told CNBC. However, the company may open new war rooms for future elections.

A report from Bloomberg Monday said Facebook was shutting down its "war room" effort. Bloomberg later updated its story to say Facebook may start new war rooms for coming elections in other countries.

The makeshift control center of sorts was part of Facebook's ongoing efforts to contain the spread of misinformation and abusive content on the platform. Foreign accounts were first found to have interfered in U.S. elections during the 2016 presidential contest and have continued the misinformation efforts since.

The "war room" also garnered heavy media attention, leading some to speculate it was a public relations stunt.

The "war room" was intended to bring employees from across Facebook's divisions together in one room to improve threat prevention and detection around the midterm elections. Facebook also deployed it during Brazil's presidential election in October.
