about this new rule that will allow the administration potentially to detain migrant families with children indefinitely. right now a court ruling limits the detentions of migrant children to 20 days, whether they are with their family or not. the trump administration has been trying to find a way around that, it goes back to the '90s. well, today's announcement is likely to hit a number of legal speed bumps because president trump believes it's all part of his effort to deter illegal immigrants from coming into the country. here is julia ainsley, of course our person who is all things immigration for us at msnbc news. i guess the shorter way to say it is he wants to be able to detain families together and deport them together. the bottom line is they do not get to spend any time out of a detention facility, when the it's in this country or mexico. >> this is the selling point,
