this week when he suggested that migrants that throw rocks at military service members at the border could be shot. he said he would advise military service members at the border to consider thrown rocks as firearms. he tried to clean that up yesterday, telling reporters he meant only that migrants that throw rocks at u.s. officials should be arrested, and the whole reason this part of the request was rejected in the first place is because arresting migrants is illegal for troops to do in the first place. but fred, this is all coming as the president tries to make deployment of potentially thousands of troops to the border to defend the border against a caravan of central american migrants, a focus of his midterm message to gop voters as he tries to inflame passions around immigration for election day. >> a partial defeat but not a complete defeat. they're still moving forward on a good part of that u.s. troops on the border plan.
