President Biden mourned with New Orleans Monday night at a prayer service at the St. Louis Cathedral.

Why it matters: The community gathering was meant to help begin the healing after a terrorist attack on Bourbon Street killed 14 people and injured at least 35 more.

The big picture: "New Orleans defines strength and resilience," Biden said, "whether it's in the form of this attack or hurricanes or superstorms. This city, its people get back up."

• He and First Lady Jill Biden laid flowers at the Bourbon Street memorial built by residents on their way to the cathedral. He also met two of the NOPD officers injured in the gunfight taking down the accused attacker.
• His comments at the service focused on grief, which he said he is too familiar with. His first wife and child were killed in a car wreck. His son died of brain cancer.
• "It's not the same," he said. "We know it's been five days staring at that empty chair around the kitchen table, without hearing their voice."
• "I promise you the day will come ... when the memory of your loved one will bring a smile to your lips before a tear to your eye. ... My prayer is that that day comes sooner rather than later."

Zoom in: Each of the names of the dead were read in the standing-room only cathedral: Kareem Badawi, Martin "Tiger" Bech, Drew Dauphin, Nikyra Cheyenne Dedeaux, William "Billy" DiMaio, Hubert Gauthreaux, Reggie Hunter, Terrence Kennedy, Nicole Perez, Edward Pettifer, LaTasha Polk, Brandon Taylor, Matthew Tenedorio and Elliot Wilkinson.

• Biden and others placed candles for the dead and injured, while more than a dozen faith leaders offered prayers for healing, unity and peace.
• There were rabbis, imams, bishops and deacons from across the city, reflecting the diversity of the victims and New Orleans. Pope Francis also sent a message.
• Gov. Jeff Landry, Mayor LaToya Cantrell, NOPD chief Anne Kirkpatrick, Congressman Troy Carter, Gayle Benson, Mitch Landrieu, City Council members, first responders, law enforcement and officials across the region packed the pews.

In the room: The feeling was solemn and surreal, with many attendees talking about events earlier in the day for Twelfth Night to kick off the Mardi Gras season.

• The Joan of Arc procession was lining up elsewhere in the French Quarter while the Voices of Peter Claver choir members were singing "Let There Be Peace on Earth" inside the cathedral.

President Biden will visit New Orleans on Monday to "grieve with the families and communities" touched by the Bourbon Street terrorist attack, the White House announced Friday morning.

Why it matters: The ISIS-inspired truck attack killed 14 people and injured dozens more.

The big picture: First Lady Jill Biden will accompany the president, the White House said.

• The statement didn't give details about where the Bidens will go or with whom they will meet.

Driving the news: Monday is also Twelfth Night, which is the official start of the Mardi Gras season in New Orleans.

• Multiple parades are scheduled that night, including the Societé Jeanne d'Arc (Joan of Arc).
• Jeanne d'Arc co-captain Antoinette De Alteriis on Thursday said its procession will continue as they hope to be a "light in the darkness."
• Carnival culminates on Mardi Gras, which is March 4 this year. See the parade schedule.

Zoom out: Biden has been in contact with Mayor LaToya Cantrell since the attack, the White House said.

• Hours after it happened, the president called it a "terrible assault," and added that "the spirit of New Orleans will never, never be defeated."
• He gave a recorded message at the start of the rescheduled Sugar Bowl too, which was played less than a mile from the crime scene.

• When Jabbar exited the truck, he began shooting, and three NOPD officers returned fire, officials have said. Two officers were among the injured.
• See the updated timeline.
• Details about victims in the attack began to emerge as loved ones learned of their identities, though New Orleans coroner Dwight McKenna said it'll take "several days" to perform all autopsies. Go deeper.
