President Trump has signed new executive orders that restrict birthright citizenship in the United States and ban birth tourism. The orders expand the existing definition of people whose children are not eligible for US citizenship at birth. They come two months after the Supreme Court ruled that Trump's earlier executive order on citizenship was unconstitutional. That ruling was issued on June 30. The new orders specifically target the practice known as birth tourism, in which people travel to the US to give birth so their child automatically becomes an American citizen. The Supreme Court had struck down Trump's previous attempt to end birthright citizenship, which is guaranteed by the 14th Amendment. The president's latest move is another effort to limit the long-standing constitutional right. No further details of the orders' implementation or legal challenges were announced.
