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

He also suggested that the U.S. troops he dispatched to the U.S.-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.
