Turner’s death comes two months into his first term representing Texas’ 18th Congressional District, the seat long occupied by former U.S. Rep. Sheila Jackson Lee, who also died in office last year amid a battle with pancreatic cancer.

Shock, dismay, and heartbreak are some of the ways Houston area leaders and Texas politicians from both sides of the aisle are reacting to the sudden passing of Congressman Sylvester Turner, former mayor of Houston.

The cause of death is unclear. Turner took office weeks ago, filling the seat left vacant by the death of Rep. Sheila Jackson Lee.
