I expect the Democrat to UNDERCUT and slam a Republican president with other countries, but for a member of the GOP to do this to a president - of either party is simply WRONG.
The president sets policy, etc. - the congress (and Senate and House together make up congress) passes laws, creates bills, debates and some get sent to the president for approval and signing. Some do not. But they do NOT set policy and they do not contradict a sitting president, period. McCain needs to GO. I think that he's been losing his mind for years and I don't refer to cancer (I'd not wish cancer on anyone)
