I haven't ever heard that, but to Guislapp's point I don't think that Trump signing an EO to remove birthright citizenship from children of illegal aliens is a good idea. I don't however think it's as cut and dry as it's made out to be. I have a few problems with the proposed executive action.
1. If the majority really want to remove automatic citizenship for children of people here illegally, the proper path is a constitutional amendment.
2. While I agree that it's a problem that needs to be solved, I don't think this is the correct way to do it. We need to focus on stopping illegal immigration in the first place and it won't be an issue.
3. Trying to solve problems with executive order is just circumventing our own processes and protections and is a continuation of Obama's legacy. This power is ripe for abuse and I think this would be an example.
