President Donald Trump said Tuesday that six people have been arrested for damaging the Lincoln Memorial Reflecting Pool, as the iconic Washington, D.C. site increasingly becomes a flashpoint over the president's $14-million-plus rehabilitation project gone awry.

In a social media post, Trump claimed without supporting evidence that there had been a "350 foot gash" in the paint as the administration faces a self-imposed deadline to fix the botched renovation before the nation's 250th anniversary celebration next week.

Trump said another seven people were cited for damaging the pool.
