State lawmakers in Texas held two hearings on Thursday to examine what went wrong during last week's fatal power outages.

The House State Affairs Committee and the Business and Commerce Committee and the Senate Business and Commerce Committee held separate hearings on the blackout.

MSNBC's Katy Tur on Thursday played a clip from one of the hearings, with a legislator discussing the toll the blackouts had taken in the Austin area.

"Harris County alone has confirmed 15 fatal cases of hypothermia including the death of a 11-year old Cristian Pineda," the legislator said, before a long pause. "Who died in his sleep after playing in the snow and returning to his unheated home. We want them and every Texan to ensure this never happens again."

Tur noted the CEO of the Electric Reliability Council of Texas (ERCOT), Bill Magness, said he had no regrets.
