Texas congressman Sylvester Turner died Wednesday, months after filling the U.S. House seat of the late Sheila Jackson Lee.

Texas Rep. Jon Rosenthal (D-Houston) offered his condolences to Turner early Wednesday morning. "He was a dear friend and an incredible lifelong public servant who will be forever remembered for his service to our communities, our city, our state and our country. RIP Mr Mayor."

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