Poverty in the United States is extensive and is deepening under the Trump administration whose policies seem aimed at removing the safety net from millions of poor, while rewarding the rich, a U.N. human rights investigator has found.

Philip Alston, U.N. special rapporteur on extreme poverty, called on U.S. authorities to provide solid social protection and address underlying problems, rather than "punishing and imprisoning the poor."

While welfare benefits and access to health insurance are being slashed, President Donald Trump's tax reform has awarded "financial windfalls" to the mega-rich and large companies, further increasing inequality, he said in a report.
