With his attacks on Rep. Elijah Cummings (D-Md.) and Cummings Baltimore district, Donald Trump is merely doubling down on his public racism.

Trump launched a Twitter attack against Cummings, calling his district “infested.” Cummings is African American.

The chairman of the House Oversight and Government Reform Committee, Cummings is leading several investigations of Trump, his business and administration.

Trump’s attack against Cummings comes right on the heels of a racist attack against four non-white Democratic congresswomen.

Although Rep. Adam Schiff (D-Calif) is another tough opponent of Trump’s, Fox News host Chris Wallace said Trump wouldn’t use the same “infested” language to attack Schiff, who is white.

“This is just who Donald Trump is. He’s just an old racist. This is how he talks about people. This is how he thinks about people,” said journalist Linette Lopez with Business Insider. “This is not a grand strategy. He’s not playing chess. He’s just a racist who uses social media.”

Trump has no agenda other than a hate agenda, according to Rep. Rashida Tlaib (D-Mich), one of the congresswomen recently the target of Trump’s racist tweets.

“The president has a hate agenda. Right now as people are in my district every single day, I talk to folks that are losing their jobs, not getting paid what they need. They’re literally working three or four jobs just to make ends meet,” Tlaib said. “So many folks at the front line are really suffering and they want somebody that’s going to follow through on reducing prescription drugs.

“But this hate agenda is now seeping into policy making. You see the deregulation in EPA and you hear from residents in down river and even in southwest Detroit, we have a right to breathe clean air,” Tlaib added. “There is something going on here. We don’t feel like our government is protecting us. And it’s because the corporation is seeping in. This is a crooked CEO in the White House that is making decisions based on profits and his friends and his for-profit industry would benefit from versus what is best for the American people. We’re not going to get played in the 13th congressional district. We can see from far away that he’s incompetent and he hasn’t followed through on the promises he made.”
