The Memo: Dangers loom for Trump on immigration

President Trump is ramping up his rhetoric on immigration, but it may not be the political winner he thinks.

On Wednesday, Trump raised the idea of abolishing “birthright citizenship” — the concept, enshrined in the Constitution, that anyone born in the United States is automatically an American citizen.

This came on the heels of a move to indefinitely extend the period for which families can be held in immigration detention facilities.
