"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."

“Cummings has been a brutal bully, shouting and screaming at the great men & women of Border Patrol about conditions at the Southern Border, when actually his Baltimore district is FAR WORSE and more dangerous,” Trump said on Twitter earlier Saturday. 


“His district is considered the Worst in the USA as proven last week during a Congressional tour, the Border is clean, efficient & well run, just very crowded. Cumming District is a disgusting, rat and rodent infested mess. If he spent more time in Baltimore, maybe he could help clean up this very dangerous & filthy place,” the president added 

Several Democratic lawmakers, including Baltimore public officials, condemned Trump's remarks as racist. Cummings, the House Oversight and Reform Committee chairman, responded to the attack by noting his role as a lawmaker. 

“Mr. President, I go home to my district daily. Each morning, I wake up, and I go and fight for my neighbors. It is my constitutional duty to conduct oversight of the Executive Branch. But, it is my moral duty to fight for my constituents,” he wrote.  

Cummings has vociferously criticized the president, and he has used his role as Oversight chairman to conduct oversight of the Trump administration. Earlier this month, he said during a committee hearing that the administration's treatment of migrant children at the southern border was "government-sponsored child abuse."
