The moment Astrid heard Obama tell her story

There was one undocumented immigrant mentioned by President Barack Obama in his speech. The BBC was with her and captured the moment of surprise - and emotion - when he did.

Astrid Silva knew the president would be addressing her and millions of other undocumented immigrants across the country, but she didn't expect him to mention her specifically by name.

President Obama described Ms Silva as a "striving, hopeful immigrant" while talking about the need for immigration reform, leading Ms Silva to break down crying while watching the speech with her father, who faces deportation.
