Trump says he will restrict asylum, claims troops will shoot at rock throwers

President Donald Trump on Thursday claimed he would sign an executive order "next week" aimed at restricting US asylum rules, as he seeks to use a group of Central American migrants heading for the US border as part of his midterm election closing argument.

He also suggested that the US troops he dispatched to the US-Mexico border could fire on someone in the migrant caravan if the person threw rocks or stones at them.

In a meandering speech at the White House about immigration, Trump recycled many of the talking points he touts on the campaign trail -- but offered little in the way of concrete ways to address the problems he embellished.

Trump said his administration is finalizing an executive action that would limit asylum claims to legal ports of entry, claiming migrants frequently abuse the system by fabricating their need for asylum.

But he declined to specify how a change he described as a forthcoming executive order would work, or why he was convening a presidential address for a policy shift that is still in the preliminary stages.
