Last year, Trump and Greenwood teamed up for the “God Bless the USA Bible.” Printed in China, it is a King James Version translation that includes copies of the U.S. Constitution, the Bill of Rights, the Declaration of Independence and the Pledge of Allegiance, as well as a handwritten chorus of the famous Greenwood song.

The country star will sing his 1984 hit song at Donald Trump's inauguration—while he continues to sell a controversial Bible inspired by that song.

The "God Bless the USA Bible," named after a hit song by Lee Greenwood, who championed the edition, finds newfound success ahead of Donald Trump's second term.
