Who does he think he is - Barack Obama?
Block them on what grounds?
Where is the legal authority to do such a thing?
This is rooted in discrimination against religious principles.
Obama is rebuilding this country into a feudal state. He himself would be the king, of course. But lesser lords, fully subservient to Obama, will be given similar absolute power over their regions. Feudalism worked for thousands of years, why not to go back to it? /s
This is quite obvious since Obama legislates from his office already by ignoring existing laws and enforcing arbitrary rules of his own invention. The Congress is silent. The Supreme Court is instructed to not interfere. The tame, bureaucratic military will not do anything. All the effective power is now in the hands of the President. This is also the point from which absolute monarchs begin their downfall. How soon The People will start seeking foreign support? And who will provide such support?
