60 years ago today, President Dwight Eisenhower signed legislation officially making “In God We Trust” our national motto.

In 1955, Eisenhower signed a bill that mandated all U.S. currency and coins bear the inscription "In God We Trust," but it wasn't officially adopted as the national motto until one year later.

Before that, there was no official motto in the U.S.

"Even though the motto was not officially adopted until 1956, it is interwoven into the fabric of this nation, from our founding documents, to our currency, to inscriptions on our government buildings," Sen. James Lankford (R-OK) and Rep. Randy Forbes (R-VA) wrote.

"America’s birth is rooted in the free exercise of religion without government coercion. This is a part of our nation’s history that cannot be erased."
