The President's Decision to Get Rid of the Programme

The president said, in january, ok, we're going to get rid of this programme. So if it is constitutional and statutorily authorized by congress, why the change in january? And what's happened in the interim,. i think in october, on the seventeenth, you issued an interim report on that. Bob, can you talk a little bit about a p d 28 and the announcement in january about the changes to two 15? I'm hopeful it will pass congress in the lame duck session, an we won't have to start all over again in a new congress.
