A North Texas girl who battled cancer is teaching Congress members regarding how to combat for what you believe in. She has collaborated with a powerful Texas congressman for a second time.

Sadie Keller was diagnosed with deadly disease Cancer, leukemia when she was 7-years-old and in the second grade.

"Hearing the words cancer whenever I was that young just was really scary," she said. "I've been through a lot of hard stuff."

Sadie began assembling toys for young patients fighting with cancer despite her own sickness who were stuck in the infirmary at crucial days like Christmas. Her gift delivery has been named as Sadie's Sleigh.

The 10-year-old Dallas resident is teaming up with Mike McCaul, Congressman to not only make them blissful but as well vigorous over again.

"When I first met Sadie, she was in remission at the time," Rep. McCaul said.

Sadie lobbied Congress with Rep. McCaul in 2015 to pass a bill that would enable the best adult treatment for cancer to be studied for use in children.

"It's the advocates like Sadie that really get members of Congress. They can say no to me but they can’t say no to her," he said.

The two are back at it on Capitol Hill once again this year to acquire lawmakers to pass the Childhood Cancer Survivorship, Treatment, Access and Research Act.

The legislation authorizes $30 million per year from 2019 to 2023 for research and programs related straight to childhood cancer.

"It's probably the most comprehensive childhood cancer bill passed by the Congress. It's gonna move things forward in terms of funding, in terms of research that we can do and in terms of doctors being able to share information," McCaul said.

The bill is expected to be approved by the president that all began with Sadie's idea for McCaul.

"We're a great team together. You know, to get a bill passed in the Congress it’s not an easy task these days and its bi-partisan. Everybody loves little Sadie." McCaul said.
