Washington, D.C., District Attorney Jeanine Pirro on Sunday said vandalism to the Lincoln Memorial Reflecting Pool that promotes algal blooms will be met with “serious charges” as workers scramble to repair President Donald Trump’s multimillion-dollar beautification project.

As part of his plan to revamp and clean the Reflecting Pool, Trump had the bottom painted “American flag blue,” but shortly after the pool was refilled, algae took over, and the blue paint started coming up.
