Per sworn duty, take care that the 1st amendment is executed faithfully and remove "God" from currency and pledge.

The U.S. Constitution explicitly spells out a duty of the President to "take care that the laws are executed faithfully". And furthermore that the U.S. Constitution is the "Supreme Law of the Land". Among this supreme law is the "Bill of Rights", the first one of which states "Congress shall make no law respecting an establishment of religion or abridging the free exercise thereof."

Both by giving special privilege to certain beliefs, and by marginalizing others, as well as the lack of belief. Same goes for the altered pledge of allegiance: "One nation, under god..." -- this must be returned to the original "One nation, indivisible..."
