Dax Tejera, executive producer of ABC News’ Sunday public affairs show This Week, has passed away at the age of 37.

In a memo released by ABC News President Kim Godwin, Tejera reportedly died from a sudden heart attack on Dec. 23.

"As EP of “This Week with George Stephanopoulos” Dax’s energy, passion and love for that show, ABC News, and you, shined every Sunday morning," the memo said. "That same love was extended to his precious girls.”

Joining ABC in 2017, Tejera began with producing remote-anchor broadcasts done across the country, and covered then-President Donald Trump’s summits with Kim Jong-Un and Vladamir Putin.

He would go on to cover topics like the Jan. 6 attack on the U.S. capitol, the Covid-19 pandemic, the 2020 presidential election, and multiple newsmaker interviews.

Tejera would go on to become the producer for This Week in 2020, the show rising to become the top show among Sunday shows for adults aged 25-54.

Prior to his work at ABC, he was a producer for MSNBC, and produced the documentary Hate Rising with HBO. He was a graduate of Dartmouth with a bachelor’s in history, before attending Columbia’s Graduate School of Journalism.

Several of his peers have expressed their grief at his passing, including ABC News senior national correspondent Jim Avila, who in a tweet said:

“Sad day for abc. A good friend and groundbreaking ABC executive passes unexpectedly at 37. Dax Tejera i only have good thoughts my friend.”

Tejera is survived by his wife, Veronica, and their two young daughters.

ABC will share more information in the coming days.
