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

The National Park Service reported that a liner along the bottom of the Reflecting Pool was cut with a sharp knife or razor, damaging foam sealant installed during the renovation. That disclosure is the first detailed account of how some damage occurred after work was largely completed. However, FactCheck.org found the administration has not publicly provided evidence to substantiate broader presidential claims about widespread vandalism, leaving unanswered questions about the full scope and cause of the problems.
