Democratic presidential nominee Joe Biden gave a speech in Pittsburgh, Pennsylvania, Monday, blaming Trump for the recent violence.

Joe Biden: “This president, long ago, forfeited any moral leadership in this country. He can’t stop the violence, because for years he has fomented it. You know, he may believe mouthing the words law and order makes him strong. But his failure to call on his own supporters to stop acting as an armed militia in this country shows how weak he is.”

Joe Biden has also come under attack from some progressives for, in the same speech, condemning what he described as “rioting” and “looting” by anti-police-brutality protesters. Princeton professor Keeanga-Yamahtta Taylor accused Biden of “walking right into Trump’s trap.”

Biden’s remarks came after Trump defended a pro-Trump rally in Portland, Oregon, in which people fired paintball guns from cars and trucks at antiracist protesters. He also tweeted a tribute to the man who was killed over the weekend, Aaron Danielson, who was known by the name Jay Bishop, during clashes in Portland, and who is believed to be associated with the far-right group Patriot Prayer. “Rest in peace, Jay!” Trump tweeted. Trump has repeatedly refused to acknowledge Black and other antiracist victims of violence.
