Democrats, grappling with years of border crises, have tried to gain ground by pointing to the bipartisan border measure that congressional Republicans blocked earlier this year after Trump came out against it. Harris on Friday lambasted Trump for his role in stymying that bill.

“It was the strongest border security bill we have seen in decades. It was endorsed by the Border Patrol union. And it should be in effect today, producing results in real time, right now, for our country,” she said at a rally in Douglas, a town on the US-Mexico border.

“But Donald Trump tanked it. He picked up the phone and called some friends in Congress and said, ‘Stop the bill,’” she said. “He prefers to run on a problem instead of fixing a problem. And the American people deserve a president who cares more about border security than playing political games and their personal political future.”
