At a campaign event today at the U.S.-Mexico border, Republican presidential candidate Donald Trump left the door open to amnesty. He did so at a press conference on the border:

A reporter asked, "Mr. Trump, what would you do with the 11 million undocument immigrants who are already here?"

"The first thing we have to do is strengthen our borders," Trump started.

The reporter interrupted, "But after that -- after that."

"And after that we're going to have plenty of time to talk about it," Trump said, failing to answer the question and then hastily ending his press conference. "Thank you very much. Thank you everybody."

Trump has not made clear how as president of the United States he would deal with the illegal immigrants already in this country. Today's press conference left the door open for some sort of amnesty in the future.
