Less than a month after opening its doors, Donald Trump's new hotel in Washington, D.C. was tagged with "Black Lives Matter" and "No Justice, No Peace" graffiti on Saturday.

According to reports, someone spray-painted the slogans on both sides of the Trump International Hotel's entrance. Pictures and videos of the graffiti, which has since been covered up with wood, were shared on social media.

Officials say they're investigating "an offense of defacing public and private property" that occurred on Saturday afternoon, according to PoliticoThe artist, who allegedly wore a yellow shirt and blue hat, added the tag "Van" but no arrests have been made yet.

Last week during the first presidential debate, Hillary Clinton said that Trump "has a long record of engaging in racist behavior." During the debate, Trump was very supportive of stop-and-frisk, which Charlamagne Tha God described on The Breakfast Club as "just an excuse for police officers to harass African-American and Hispanic people." Trump also has many neo-Nazi and white supremacist supporters, including former KKK leader David Duke. 

Trump's 263-room hotel had its soft opening in September in the 125-year-old Postmaster General's building on Pennsylvania Avenue, Politico reports. Rooms go from around $500 a night to nearly $10,000, according to Fox News. The grand opening is expected to take place in late October.
