Trump has said he will announce early this week whether he will end or continue the program initiated by former President Obama.
"Our house is just crumbling down," she told ABC News. "It's sad.”
Medrano said she dreams of becoming a surgeon but now fears she may be forced to leave the country where she has lived most of her life.
“My biggest fear is for us to get deported. For my family, all the hard work that they have done, to just get thrown away,” Medrano said. “And for me, to not be able to study, not be able to work … it's a lot. And I still have to worry about going back to school [in the wake of the Houston flooding]. So it's kind of stressful.”
Houston’s police chief Art Acevedo echoed those concerns while visiting evacuees at the city’s convention center.
“There are so many homes that have been damaged and some beyond repair in our state, and then you add on top of that all the issues with the immigration debate and all the ugliness of that,” Acevedo told Raddatz.
“I was mentioning to somebody, it's a state official that was pushing this anti-immigration ugly narrative, and I think I asked him, ‘Now what are you going to tell the American people when we scared away so many hardworking people?’”
Raddatz asked Texas Gov. Greg Abbott about Medrano.
He said the 15-year-old’s situation shows that the United States has “had an absolutely broken immigration system for decades.”
“This can has been kicked down the road for far too long and what you're talking about are very real-life consequences of this system,” Abbott said.
“Until Congress, until the United States truly reforms out immigration system with standards that everybody knows and understands that are enforced and applied, we will continue to deal with these very challenging circumstances,” he said.
“So what would you say to that 15-year-old?” Raddatz asked Abbott.
“I would say to that 15-year-old that we need to ensure that we keep America the kind of country that people want to come to,” he said. “The best place to get into is the United States of America. And we need to make sure we keep America that shining city on the hill that people aspire to.”
Raddatz pressed, “So it's not with someone like her here?”
“Well it's going to be a standard that ensures that America will be the place that people aspire to. And there will be ways, if Congress reforms the immigration system, that there will be ways which America needs to continue to attract immigration through the legal system,” the Texas governor said.
