LEGAL/OBAMA/TRAVEL BAN/TRUMP EXEC ORDER: “What limitations are there?- Only Congress can change laws or appropriate new funds from the Treasury. Presidents are required to uphold those laws and work with the resources they are given.
When presidents overstep these limits — which aren’t always precisely defined — they can be blocked by the courts.
Already, a handful of federal judges have issued rulings blocking key aspects of Trump’s travel ban.”
