House lawmakers are expected to vote, Tuesday, on a measure that would reaffirm America's national motto as "In God We Trust."
The phrase has been used on U.S. currency since the 1860s but was officially adopted as the national motto in 1956.
Still, the saying has faced several court challenges because of the use of "God."
All those challenges failed in court. However, Rep. Randy Forbes, R-Va., noted that the motto is often misstated.
For example, President Barack Obama mistakenly referred to "E Pluribus Unum" as the national motto in 2010. He later corrected himself.
Forbes, who co-chairs the Congressional Prayer Caucus, said his resolution to reaffirm the motto would also encourage leaders to display the phrase in public and government buildings.
"As our nation faces challenging times, it is appropriate for members of Congress and our nation -- like our predecessors -- to firmly declare our trust in God, believing that it will sustain us for generations to come,"Forbes said in a statement.
The resolution has 64 co-sponsors, including Republicans and Democrats.
