A prayer, they don't hold religious revivals in Congress.
But that's an interesting point. I personally don't like the fact that my tax dollars pay for a chaplain for a bunch of people with churches all around them that they could go to. Plus, the selection of a new chaplain leads to divisive sectarian strife.
Quite PC of you, and entitled to your opinion. IMO, though, America's decline in morality and common decency seemed to begin with a vengence precisely when prayer was taken out of the public schools. Could be a coincidence...
The issue of whether or not public schools, funded by taxpayers, should exist is another whole subject.
