A 10-year-old girl who died of brain cancer is leaving a legacy for other sick children in a new law signed by President Barack Obama.

Obama on Thursday signed the bipartisan Gabriella Miller Kids First Research Act. It directs $126 million in federal money to be spent over the next decade to research pediatric cancer and other childhood disorders. Her parents and brother watched Obama sign the bill.

Gabriella pushed Congress to pass the law in an emotional video posted to YouTube before she died last October. The Leesburg, Va., girl told political leaders: “Stop talking and start doing.”

The legislation calls for eliminating taxpayer funding for political conventions and redirecting it to pediatric research at the National Institutes of Health.

Congress must fund the research in future spending bills.
