Trump’s birthright citizenship attack the latest effort in obsessive campaign

For more than a decade, president has been fixated on trying to undermine a key constitutional right

With a pair of executive orders on Thursday, Donald Trump has tried – once again – to undermine the guarantee of birthright citizenship, a right enshrined in the US constitution and reaffirmed by the supreme court just five weeks ago.

The orders attempt to broaden the categories of children who would be ineligible for automatic US citizenship and ban so-called “birth tourism”, which the president claimed is practiced by “hundreds of thousands” of people.
