Julia Letlow (R) on Saturday won Louisiana's 5th congressional district's special election for the U.S. House, AP reports.

Why it matters: Letlow will now replace her late husband, Rep.-elect Luke Letlow (R), who passed away from COVID-19 in December. He was just 41 years old. She received a resounding endorsement from former President Trump, who said she is "so outstanding."

The big picture: Letlow's race is not the only special election in 2021 that's been prompted by a member of Congress passing from COVID-19.

• Rep. Ron Wright (R-Texas) also passed in February from COVID-19. His wife, Susan Wright, is similarly running to take his seat.
