According to Christian News:
A prominent professing atheist group has sent a letter to Florida Sen. Marco Rubio, urging him to stop sharing Bible verses on his official Twitter account, which they say violates the separation of Church and State.
The Wisconsin-based Freedom From Religion Foundation (FFRF) sent the letter on Aug. 22, noting that Rubio has tweeted over 60 Scriptures in the past three months. It asserted Rubio is violating the Constitution since he is posting the messages on what the group perceives as being a government-related account, not a private and personal account focusing on his home and family life.
