Authorities began installing fencing and cameras around the Lincoln Memorial Reflecting Pool as President Donald Trump alleges vandals have been destroying the administration’s multimillion-dollar renovations at the site.

Workers began erecting a chain-link fence around the pool’s perimeter on Tuesday evening, alongside overhead cameras installed by the pool’s edge, which can be seen in a livestream video from MS NOW. A spokesperson for the Interior Department told the Washington Examiner the fencing was set to go up before July 4 celebrations but was installed early because of the alleged vandalism.
