President Trump just introduced his youngest guest: 10-year-old Grace Eline.
"Joining Melania in the gallery this evening is a very brave 10-year-old girl, Grace Eline," Trump said. "Every birthday since she was 4, Grace asked her friends to donate to St. Jude's children's hospital. She did not know that one day she might be a patient herself."
About Grace: At 9 years old, Eline was diagnosed with germinoma, a type of brain cancer.
"Grace recently finished chemotherapy and today shows no evidence of the disease. She is determined to help other children who are fighting cancer," said the White House.
