Guatemalan Asylum seeker Beata Mejia Mejia was finally reunited with her 7-year-old son on Friday.
The boy was taken by immigration authorities in May and was placed in a child detention centre along with 2,300 other migrant children.
The official reason Mejia-Mejia and her son were separated is that they didn't make their asylum claim at a port of entry.
After a national outcry, Trump signed an executive order on Wednesday rescinding the decision to separate parents from their children.
