More racist comments from Trump | He called "catastrophe …

US President Donald Trump has made racist and xenophobic comments by attacking an African-American legislator and calling the city of Baltimore, for the most part black, a "disgusting disaster."

Trump's words came in a series of tweets addressed to Democratic Representative Elijah Cummings, a strong critic of the Republican government whose district covers much of Baltimore. "The district of Cumming (sic) is a disgusting disaster, infested with rats and rodents," the president wrote, calling it "the worst and most dangerous" in the country.

"No human being would want to live there," he said in an attack apparently provoked by Cummings' critics over the harsh conditions faced by asylum seekers on the Mexican border. .

"Cummings has been a brutal thug, shouting at the border patrol men and women of the situation on the southern border, while their Baltimore district is MUCH MUCH worse and more dangerous," Trump said.

Lawmaker Cummings responded in the same social network: "Mr. President, I go to my district every day, every morning I get up and fight for my neighbors.It is my constitutional duty to supervise executive power.But it is my moral duty to fight for my constituents. "

As chair of the House of Representatives' oversight committee, Cummings has investigated government policies, including reports of mistreatment in immigration detention centers.

This new xenophobic message from the president provoked a storm of criticism less than two weeks after the House of Representatives condemned him for racist remarks to Somali-born legislator Ilhan Omar.

"We reject the racist attacks against him and support his strong leadership," Nancy Pelosi, Democratic Chair of the House of Representatives whose father was mayor of Baltimore, said on Twitter. "Cummings is an advocate for civil rights and economic justice at home and in the country, a beloved leader in Baltimore and a valued colleague," tweeted Pelosi.

The port city of Baltimore has a dual image, with its beautiful and rich neighborhoods and large neighborhoods affected by poverty. The homicide rate is one of the highest in the country. More than half of the population in Cummings District is black.

Trump recently attacked four young Democratic lawmakers, descendants of immigrants, whom he suggested to return to their country.
