Adam Slee, Duncan Grimmond, Norman Miller and Dr Bruce Lloyd dissect the US president’s recent racist abuse towards four US congresswomenDonald Trump has suggested that certain US congresswomen might go back to “the totally broken and crime-infested places from which they came” (Trump intensifies racist attack on congresswomen despite outrage, 16 July). How sad to be chief of state of any of those countries. Alexandria Ocasio-Cortez’s mother came from Puerto Rico. Her father was of Puerto Rican origin, though himself born in the Bronx. The chief of state of Puerto Rico? President Donald J Trump.
• Woody Guthrie wrote a song about a notorious apartment block built by Donald Trump’s father. Black people were free to apply but none were acceptable as tenants. Racism is generally learned in the home.
