You counting on “quickly” protest too much.
“Quickly” does not apply to the immigration process. Going to the back of the line means “quickly” is about ten years of process, consideration and assessment.
Could you post quotes from Trump or his son saying that illegals would go to the back of the line?
All I can find is quotes saying that the process would be expedited for the illegals who want to return legally (not necessarily as citizens, just “back” legally) and that he’ll do something else for DREAMers.
I can’t find any quotes where he uses the term expedited for those who’ve been waiting in line for years or where he says illegals will go to the back of the line.
