Thank you.
I would say once again that it's important to make a distinction between the U.S. requirements and the Canadian requirements. I think it is the U.S. position that the alternate documents are the passport or the NEXUS card as their passport card. They've been working very hard to encourage people to get it. The reason they're doing so is that it contains an RFID chip, which gives people the ability to get into the so-called fast lanes to move more expeditiously through the border.
But I'm not aware of any formal discussions around Congresswoman Slaughter's idea.
