Someone needs to tell little Lester that there is a reason that Lady Liberty is located on Liberty Island next to Ellis Island where legal immigrants were processed and not the Mexican border where they come through with no papers.
Someone needs to remind Holt that immigrants were detained and sent back home at Ellis Island, too.
ELLIS ISLAND HISTORY - ARRIVAL
Despite the island's reputation as an "Island of Tears", the vast majority of immigrants were treated courteously and respectfully, and were free to begin their new lives in America after only a few short hours on Ellis Island. Only two percent of the arriving immigrants were excluded from entry. The two main reasons why an immigrant would be excluded were if a doctor diagnosed that the immigrant had a contagious disease that would endanger the public health or if a legal inspector thought the immigrant was likely to become a public charge or an illegal contract laborer.

I don't know what Trump hopes to replace this EO with, but equal numbers of males and females would be preferable. To "level the playing field", as the Dims often cite.
