"This is not an incidental loss amid conflict - it is a calculated endeavour to erase Sudan's legacy, to sever its people from their past, and to plunder millennia of human history for profit."
One of the men, Timothy Wallis, told the Associated Press news agency his friends had just bought the Trump hats from a street vendor.Mr Wallis, 58, of Pocatello, Idaho, said the People's March protesters had "every right" to demonstrate, though he said he was confused by the rancour.
"It's sad where we're at as a country," he said.Another protester the BBC spoke to, came to Washington specifically for the march.Susie came in from the San Francisco area to demonstrate with her sister, Anne, who lives nearby. They both attended the Women's March after Trump's first inauguration and came back in their "pussy hats".
Susie recalled the crowds of people in 2017. She said she hoped people would still take to the streets against Trump's policies."This time the stakes are higher," she said. "Trump has been emboldened. He's got the billionaire class and the tech class bowing down."
Anne also said she recognised the protesters are "out of touch" with a lot of America. Trump won all seven swing states and the popular vote last November.
But she added: "We're still here, and we will resist."Many people cannot get to the market "and if they go, they find high prices", explains Manahel.
"Every family is equal now - there is no rich or poor. People can't afford the basic necessities like food."After cooking meals such as rice and stew, they deliver the food to people in shelters. For many, it is the only meal they will have for the day.
When the war started, Manahel had just finished university, where she studied Sharia and law.As the fighting reached el-Fasher, she moved with her mother and six siblings to a safer area, further away from the front line.
