The family of Jahi McMath is fighting to keep the 13-year-old on life support at Children’s Hospital Oakland after the teen was declared brain dead following a tonsillectomy that prompted a heart attack. NBC Bay Area reports:

Her family has taken to the media, and threatened to involve lawyers, after they feel something went horribly wrong following Jahi’s Dec. 9 tonsillectomy to help cure her sleep apnea. Following the surgery, relatives said Jahi was alert and asking for a popsicle. But 30 minutes later, she was choking up blood and went into cardiac arrest for reasons unexplained.

Jahi’s family has also reached out to Oakland Mayor Jean Quan to see if she can help delay the hospital from taking the girl off life support. It is unclear what action, if any, Quan will take.

Dr. David Durand, the head of pediatrics, told the family that they will take Jahi off life support Tuesday, though the girl’s family said earlier they were vehemently against that.

Under California law, “A person who is declared brain dead is legally and physiologically dead.”

Twitter has come together to support the McMath family under the #PrayersForJahi hashtag.

Our thoughts and prayers are with the McMath family as well.
