If nothing else, Franklin Graham. Before doing his own little things outside the Pentagon and on Capitol Hill, he had this to say to Fox:

The Muslims have their holidays that they celebrate at the Pentagon.
They celebrated Ramadan. They have prayer services there. But for us
Christians to have prayer services, and for them to object and for the
Army to give in to their objections is something that I
just don’t understand.

Leave aside the misapprehension (which he seems to have gotten straight today) that it was “the Muslims” rather than Mikey Weinstein who objected to his Pentagon appearance. Graham thinks that the National Day of Prayer is a Christian holiday, as per the National Day of Prayer Task Force, which he co-chairs:

The National Day of Prayer Task
Force’s mission is to communicate with every individual the need for
personal repentance and prayer, mobilizing the Christian community to
intercede for America and its leadership…

And now Graham’s going after the president? Enough already.
