This isn't good [2]. It seems the Secret Service is running short of manpower, considering they've got so many presidential candidates they may have to eventually offer protection to, (currently about 20). As a result, they're planning to "borrow" about 2,000 immigration officers and airport screeners to help do the job.
I guess they figure that, since that immigration amnesty bill might pass, all those immigration agents would be sitting around with nothing better to do.
