The quote from that source is:
“I say to their parents: Thank you for bringing these Dreamers to America. We’re in your debt for the courage it took, for you to take the risk, physically, politically, in every way, to do so,"
Which is still not the fake quote in the meme.
Not sure why she means about being in their debt, since it's pretty much the other way around. Basic pandering. Maybe she should repay that "debt" by inviting them to stay at her place.
(Wish I already had a pic set to go from High Plains Drifter for that last bit there)
