Reflecting Pool liner was cut with a sharp knife or razor, National Park Service says

The National Park Service reported that the liner of the Lincoln Memorial Reflecting Pool was intentionally cut with a sharp knife or razor in June, damaging foam sealant installed during a $16 million rehabilitation project. The reporting is sourced from a named NPS official and appears in multiple major outlets (NPR/AP, NBC News, USA Today, WRAL), indicating corroborated basic facts about the alleged vandalism and the damage to recent improvements. However, as noted in USA Today's coverage, the reporting lacks specificity about investigative methodology—NPS officials have not publicly detailed how they determined the cutting method, whether forensic analysis was conducted, or what evidence supports their conclusion. Watch for developments from US Park Police's investigation, including any release of additional surveillance footage or identification of suspects, which would help clarify the circumstances and intent behind the damage.
