The NPS leader’s statement gave no indication of how officials arrived at the conclusion the multi-million dollar liner was cut. Park officials did not answer requests for comment.A top National Park Service official said in a sworn declaration before a federal court that President Donald Trump’s revamped Lincoln Memorial Reflecting Pool was vandalized using a "sharp knife or razor." The park service's deputy director for operations, Frank Lands, said in his sworn statement that the Reflecting Pool liner the Trump administration ordered redone ahead of the nation’s 250th anniversary was deliberately cut. Lands’ statement gives no indication of how park officials concluded the liner was cut using a knife of some kind. The statement was filed June 24 with the U.S. District Court for the District of Columbia. It’s the latest filing in connection with a lawsuit arguing that the Trump administration illegally renovated the iconic Washington fixture.According to Lands, the park service reported the vandalism to U.S. Park Police and officers responded June 9. Park police work within the park service. Park service officials did not immediately respond to requests for comment on Lands’ declaration, including how officials determined the liner was cut.The pool, a must-see stop along Washington’s Monument Row, has become a point of controversy since Trump in April announced a project to resurface and paint the bottom of the shallow pool "American Flag blue."The announcement was controversial for several reasons. Among them, the Trump administration bypassed the typical competitive bidding process for the multimillion-dollar renovations, and among contractors Trump hired was a company linked to a Trump donor.The renovated pool also quickly deteriorated. A massive algae bloom turned the water lime green, and the new surface liner has come off in visible sheets. Trump has said publicly that the pool’s new surface has come apart because of vandalism.
