Rep. Ted Lieu takes shot at Trump's ancestors after president calls for only admitting immigrants based on 'merit'

Replying to a tweet by President Donald Trump, who slurred amnesty-seeking immigrants as "these people" before saying he wanted a merit-based system of admitting possible new U.S. citizens, Rep. Ted Lieu (D-CA) reminded the president of his own ancestors' humble beginnings.

On Twitter Trump wrote, "We cannot allow all of these people to invade our Country. When somebody comes in, we must immediately, with no Judges or Court Cases, bring them back from where they came. Our system is a mockery to good immigration policy and Law and Order. Most children come without parents," before adding, "Immigration must be based on merit – we need people who will help to Make America Great Again!”

According to Lieu, there was little Trump's ancestors had to offer when they came over on the boat -- and he reminded Trump on Twitter.

"Dear @realDonaldTrump: I will support merit based immigration based on the same standards that allowed your grandfather, who started off poor & as a barber, to immigrate to America as an unaccompanied minor," he tweeted before adding a puckish, "#SundayMorning Thoughts."
