Sen. Bernard Sanders accused President Trump on Sunday of using his “extreme vetting” order and raids on illegal immigrants to distract from his decision to stack the Cabinet with bankers and billionaires and potentially overhaul popular health programs. Mr. Sanders , Vermont independent and hero of the progressive left, said U.S. vetting systems are “very, very strong,” so Mr. Trump should not be trying to temporarily halt the American refugee program or migrants from seven predominantly Muslim countries.
