[Notwithstanding]

The constitution forbids only establishment - which is far far different than the constitutionally permissible government involvement with or promotion of religion.

Since it is permissible, such promotion or involvement can be legislatively required or prohibited.

(Unlike a constitutional freedom or right - such as to bear arms - which cannot be suppressed via legislative act)

[Double Tap]

"Congress shall make no laws respecting an establishment of religion, or prohibiting the free exercise thereof;..." Amendment I, Bill of Rights.

So if congress can make no law respecting any religion, how can they do what he says?
