who covers national security for nbc news. so let's just say we take from that statement that the white house is not happy with the documents. do they have a choice though of whether or not to comply, ken? >> the reality is the white house has a lot of ways at their disposal to resist the requests. so when you see former white house officials on this list like former chief of staff or former spokesman sean spicer, you can expect the white house will assert executive privilege and resist document requests regarding those people and things that happened in the white house and they can be successful in that. there was a case in the obama administration, the fast and furious scandal, it took six years for a judge to rule on a house subpoena there. obama was out of office. it's actually hard to enforce a congressional subpoena. that said, many of the people on this list are private individuals, unconnected to the white house. congress is likely to be much more successful to get documents
