With all due respect for Judy Woodruff, I must correct her constantly telling Kenneth Cuccinelli about how America has always welcomed the poor, downtrodden, etc., with open arms: Following WWII, the Jews that survived the Holocaust were required to secure American sponsors (usually family members already living here) that would sign affidavits guaranteeing that they would support the Jewish immigrants so that the immigrants would not burden the American taxpayer or the welfare system, such that it was.
If you couldn't get a sponsor -- you didn't get in. Thousands of Holocaust survivors sat in displaced persons camps (some of which were the very concentration camps that imprisoned them) for several years -- until 1948 when the State of Israel was declared.
