President Trump doubled down on his criticisms against Rep. Elijah Cummings on Sunday, defending himself against allegations of racism.

Trump has targeted Cummings over the Maryland Democrat’s own attacks against Trump’s immigration policies and because of attempts by House Democrats to push the Russian collusion narrative and charge the president with obstruction.

"Someone please explain to Nancy Pelosi, who was recently called racist by those in her own party, that there is nothing wrong with bringing out the very obvious fact that Congressman Elijah Cummings has done a very poor job for his district and the City of Baltimore," Trump tweeted.

"Just take a look, the facts speak far louder than words! The Democrats always play the Race Card, when in fact they have done so little for our Nation’s great African American people. Now, lowest unemployment in U.S. history, and only getting better. Elijah Cummings has failed badly!" Trump said.

Trump's tweets follow similar statements made Saturday. The president accused Cummings of failing his "his very poor, very dangerous and very badly run district" and shared several videos depicting trash-strewn areas around Baltimore.

Cummings is chairman of the House Committee on Oversight and Reform. He defended himself Saturday, tweeting:

"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."

Cummings also called on Trump to work with him on legislation to bring down the cost of prescription drugs.
