Letlow, 41, announced on December 18 that he had tested positive for the novel coronavirus.
“It is with heavy hearts that @FirstLadyOfLA and I offer our condolences to Congressman-elect Luke Letlow’s family on his passing after a battle with COVID-19,” Edwards said on Twitter.
Letlow, who served as chief of staff to former Rep. Ralph Abraham (R-La.) before being elected to fill that seat, was supposed to be sworn into Congress on Sunday. He is the first member or member-elect to die from the coronavirus, though dozens of lawmakers have tested positive for Covid-19 over the past year.
