EL PASO, Texas — Democratic presidential candidate Beto O’Rouke on Saturday joined a march in the Texas border city of El Paso to condemn last week’s mass shooting there, telling the crowd that President Donald Trump was partly responsible for the hatred that inspired it.

O’Rourke has said the Republican President has stoked racial divisions with his harsh words and policies to stem the flow of immigrants into the United States.

Trump on Wednesday said on Twitter, “The Dems new weapon is actually their old weapon, one which they never cease to use when they are down, or run out of facts, RACISM!”

Jessica Coca Garcia, who was shot in the legs last Saturday and whose husband also was wounded in the Walmart attack, struggled to rise from a wheelchair to speak to the crowd.

“Racism is something I always wanted to think didn’t exist,” she said. “Obviously it does.”
