In the Episcopal Church the leaders of the country are prayed for every Sunday.

Also the leaders of the community.

This has been the case for at least 237 years. The G. W. Bush administration launched an IRS investigation against the Church in 2005. The Church made it clear that under no circumstances did they intend to do anything differently.

After a few years the IRS dropped their investigation. The IRS never said why.

This did seem to me to be a Church/State matter, but perhaps they were Grandfathered in. Or maybe it was because more Presidents of the US have been Episcopalians than any other faith.
