WASHINGTON — The White House released on Monday the list of people President Trump and his wife, Melania, invited to attend the State of the Union address, scheduled for Tuesday night.

An eclectic cohort will join the first lady: emergency medical workers, service members and faces of Mr. Trump’s tax and immigration overhaul narratives. Here is a preview of who you’ll see:

Official and unofficial emergency responders

David Dahlberg, a fire prevention technician, who saved 62 children and staff members from a blaze-encircled summer camp in July during the wildfires in Southern California.

Ashlee Leppert, an aviation electronics technician in the Coast Guard, who rescued dozens from hurricane ruins. According to the White House, Ms. Leppert operated a helicopter basket that hoisted to safety a woman who was clutching four children at once.

Jon Bridgers, the founder of the “Cajun Navy,” a nonprofit rescue team that served in Texas during Hurricane Harvey. In 2016, Mr. Bridgers founded the organization in response to flooding in Louisiana and continues to collect donations for areas still devastated.
