She does not want a child if it is not going to be a US Citizen Anchor Baby. Disgusting.
Deport her today and she can get her abortion in Mexico.
Something like 66% of all abortions in the USA are committed in the first 8 weeks, and 90%+ in the first 12 weeks. It's highly unusual for a girl/woman who actually wants an abortion, to let it go to 15 weeks. She's probably already feeling the baby's movement.
I catch a whiff of coercion here.
