Celebrity real estate developer Donald Trump is blaming President Barack Obama for the unrest in Baltimore.

Trump, a frequent Obama critic, ripped the president on Twitter early Tuesday.

He wrote: “Our great African American president hasn’t exactly had a positive impact on the thugs who are happily and openly destroying Baltimore.”

Trump also criticized the Baltimore police and the city’s mayor.

Riots erupted in the Maryland city Monday after the funeral of Freddie Gray. The unarmed man died after suffering a spinal cord injury while in police custody.

Trump has frequently hinted at running for president and is doing so again this year.

He has never followed through with an actual candidacy.

A request to Trump for comment was not immediately returned.
