Hours ahead of President Joe Biden’s visit on Monday to New Orleans — his first since the violent attack on New Year’s Day that left 14 people dead — law enforcement officers swarmed a blockaded Jackson Square, where Biden and his wife, first lady Jill Biden, were expected to attend an evening prayer and memorial service at St. Louis Cathedral.

In New Orleans, the driver plowed into a crowd on the city’s famous Bourbon Street. Fourteen revelers were killed along with the driver. Shamsud-Din Jabbar, who steered his speeding truck around a barricade and plowed into the crowd, later was fatally shot in a firefight with police.
