In a lunch meeting with television anchors before the president's address to Congress Tuesday — a meeting that has traditionally been largely off the record — President Trump said he was open to another attempt at an immigration overhaul.Initially, the White House (which has been critical of anonymous sourcing) insisted that the news not be attributed to the president.John Yang of the PBS NewsHour was among those in attendance:As a candidate, Trump shot to prominence by pledging to build a wall on the border with Mexico. In a document posted on his campaign website, Trump criticized the immigration law passed by the Senate in 2013. The House never took it up."When politicians talk about 'immigration reform' they mean: amnesty, cheap labor and open borders," the document says. "The Schumer-Rubio immigration bill was nothing more than a giveaway to the corporate patrons who run both parties. Real immigration reform puts the needs of working people first — not wealthy globetrotting donors. We are the only country in the world whose immigration system puts the needs of other nations ahead of our own. That must change."Another immigration policy document posted on the Trump campaign website but later removed included a 10-point plan "to put America first." The 10th item on that list: "Reform legal immigration to serve the best interests of America and its workers."Which is to say Trump has never outright opposed immigration reform, but exactly what he envisions has never been clear. There's much more clarity on immigration enforcement, sanctuary cities and border protection.Exactly what the president is contemplating now isn't clear, as AP's Julie Pace reports. The White House indicated Trump is, in fact, open to doing something on immigration reform."I do know that the president has been very clear in his process that the immigration system is broken and needs massive reform," White House spokesman Sarah Huckabee Sanders said. "And he's made clear that he's open to having conversations about that."This isn't the first time Trump has expressed an openness to pursuing immigration reform. Earlier this month, the Washington Post reported that he discussed it with senators he had invited to join him for lunch at the White House:
