Sweet gentle Jesus this story is a microcosm of one of the major things wrong with our country. Any idiot with an Internet connection is a journalist. Now we can have a discussion about the EO in question but let's get a few facts out on the table in regards to this "news".
1. This woman was not deported. And as some one posted earlier in this thread she wasn't "effectively" deported. She left the country of her on volition and was denied reentry. This is in no way shape or form deportation.
2. She is not a Clemson professor. She was a TA while completing her PHD at Clemson. Additionally she is not currently employeed by Clemson. Per her own public information she is a data analyst for a small startup. She has no more or less affiliation with Clemson than any other alumnus. I have a theory why the Clemson connection was used but that is another discussion.
3. No one knows what the status of her visa or what particular visa she was using to be legally in the USA.
4. If her visa was expired, that alone even without the EO, is enough to deny someone entry.
5. The EO is TEMPORARY. If people would stop getting their news from baseless sources in Twitter and actually read the EO you would know this.
Now we can go on to debate the pros and cons of the EO but this thread title is a lie as well as the cited source (a tweet from some twit). If we can't start with the same set of facts then the discussion is pointless.
This second letter in this blog post seems to be about her: http://www.theamericanconservative.com/dreher/readers-on-trumps-immigration-ban/
