President Trump said he will work with African American Republican Kimberly Klacik running for the late Rep. Elijah Cummings’ congressional seat, saying “we will bring Baltimore back.”

“Kimberly will work with the Trump Administration and we will bring Baltimore back, and fast,” the president posted on Twitter Tuesday, referring to Klacik.

“Don’t blow it Baltimore, the Democrats have destroyed your city!” Trump continued.

Trump linked to a viral video posted by Klacik that blamed Baltimore’s leaders for allowing the city to deteriorate into a hub of poverty and crime.

“Do you care about black lives? The people that run Baltimore don’t. I can prove it. Walk with me. They don’t want you to see this,” Klacik said in the ad showing her on a walking tour of the district once represented by Cummings, who died last October.

“This is the reality for black people every single day: crumbling infrastructure, abandoned homes, poverty and crime. Baltimore has been run by the Democrat Party for 53 years. What is the result of their decades of leadership?” she said as she walked among dilapidated buildings.

She is attempting to flip the seat and urged voters in the video to oust Rep. Kweisi Mfume, who won an April election to fill Cummings’ seat, beating Klacik by nearly 49 points.

Klacik, 38, and Mfume, a former president of the NAACP, will face off again this November.
