David Simon, the creator of "The Wire," an HBO series set in Baltimore, on Saturday denounced President Trump Donald John TrumpSteele Dossier sub-source was subject of FBI counterintelligence probe Pelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' Trump 'no longer angry' at Romney because of Supreme Court stance MORE as an "empty-suit, race-hating fraud" following his attacks on Rep.

"If this empty-suit, race-hating fraud had to actually visit West Baltimore for five minutes and meet any of the American citizens who endure there, he’d wet himself," Simon said on Twitter moments after Trump targeted Cummings and his congressional district.

Simon added later that the "president is 'literally' a simplistic, racist moron."

"I am 'literally' the guy writing stuff about the last century of U.S. policy, about the drug war and mass incarceration, about Brown v. and white flight, about all of modern U.S. history to which your kind stays mute," he said in a tweet defending his criticism.

"The Wire" was a renowned HBO series that documented many issues facing the city of Baltimore, including drug abuse and police corruption. Simon served as the show's executive producer and head writer.

Simon's criticism of Trump came after the president referred to Cummings's district as "dangerous" and a "rodent infested mess."
