Do we have our first full-blown diplomatic incident marring the carefully orchestrated visit of Pope Francis to the U.S.?

Did the Obama White House muff what should have been a slam dunk in welcoming the pontiff to what is essentially a Washington photo op?

It sure sounds that way judging by the conservative outrage over White House invitations to a number of gay Catholics and LGBT advocates, an openly gay Episcopal bishop and a nun who is a prominent social justice activist.

They are among the nearly 15,000 people taking part in a reception for Francis on the South Lawn on Wednesday(Sept. 23) before his private meeting with the president.
