National Guard Deployed at Lincoln Memorial Reflecting Pool After Vandalism

National Guard troops and police have been posted at the Lincoln Memorial reflecting pool in Washington, D.C., after repeated acts of vandalism damaged the recently repaired structure. Pieces of the pool floor have been removed and new sealant has been cut. Investigators found the numbers "8647" scratched into the sealant, a reference some interpret as a threat.

Multiple people have been arrested at the site.

Some were detained while attempting to damage the pool, while others interfered with workers removing algae from the water. One man was stopped carrying a pitchfork and bucket near the pool. Another was arrested after grabbing a hose from workers cleaning the algae.

The incidents follow recent work to address algae growth and leakage at the pool. Similar algae appeared after earlier renovations completed between 2010 and 2012. Officials have installed surveillance equipment and increased patrols to prevent further damage.
