A loud groaning noise at Tuesday's White House press briefing wasn't 'Lincoln's ghost.' It was a creaky robot.

• A loud creaking noise interrupted Tuesday's White House press briefing.
• One reporter at the press conference joked that it might have been "Lincoln's ghost."
• The loud sound was actually a robotic camera swiveling in place.

A loud creaking noise interrupted Tuesday's White House press briefing, but it wasn't a crumbling roof or "Lincoln's ghost," as some suggested: the culprit was a robotic camera.

As White House Press Secretary Jen Psaki was answering a question about the CDC's recent change to mask-wearing recommendations, a groaning sound rang out.

"Have no fear, the ceiling is not falling... that I'm aware of," Psaki said after pausing. One reporter called out that the sound was may have been "Lincoln's ghost."

Reuters White House correspondent Steve Holland later said that the source of the eerie sound was much less supernatural. It was, in fact, a robotic camera attached to the ceiling that was swiveling in place.
