Is it true that Obama has a prayer cloth as a back drop and not an American flag

No Obama couldn't pardon Gitmo detainiees as they were never convicted but the ex sheriff was convicted in an American court for committing crimes

No, it is not.

The birth certificate is a red herring invented by Hillary Clinton. His mother was a US citizen so he was born a citizen. His citizenship was renounced by his guardian when he was enrolled in the Indonesian Madrassas and there is no record of restoration. He "attended" college as an immigrant and was promoted because he was a twofer -- an immigrant and black.
The Qur'an in a variety of verses (2:225, 3:28, 3:54, 9:3, 16:106, 40:28, and 66:2) establishes the religious legitimacy of breaking oaths, lying, unilaterally violating treaties, and generally scheming against non-Muslims. Allah himself is described as "the best of schemers" (3:54, 8:30, 10:21), and Muhammad declared, as a justification for murdering unarmed prisoners after offering them safe passage, "war is deceit" (see the Hadith collection of Bukhari, vol. 4, book 52, numbers 268-271)

If anybody wants to pray for the good old USofA then do it now before trump gets to start a nuclear holocaust that will destroy 1/2 the world with USA at the center of that destruction

Not a router question, but I assume you're talking about a press conference on June 13, 2014, where he was asked about the exchange of Taliban prisoners for an American serviceman held by the Taliban.

The remark that got the most press was: "But this is what happens at the end of wars. That was true for George Washington; that was true for Abraham Lincoln; that was true for FDR; that's been true of every combat situation -- that at some point, you make sure that you try to get your folks back. And that's the right thing to do."

He didn't Public Law 100-307, as amended, has called on the President to issue each year a proclamation designating the first Thursday in May as a "National Prayer Day". By law he made national prayer day May 1st.

It offends muslims because they don't believe in God they believe in allah and Christians don't.

Inappropriate question as not a technical issue.
