Arkansas Gov. Sarah Huckabee Sanders is standing her ground by refusing to remove a chalk-drawn cross from the entrance to the governor’s mansion after Americans United for the Separation of Church and State demanded its removal, claiming it violates the U.S. Constitution.

The uproar began after Sanders shared a photograph on Facebook of her three children standing behind a large image of a cross and stained glass they colored with sidewalk chalk. Captioning the image “New artwork to welcome people into the Governor’s Mansion.”

The post provoked a response from the secular Americans United, a nonprofit organization based in Washington, D.C. The group wrote a letter to the governor, arguing that the chalk artwork conveys an “impermissible message that those who do not share the favored faith are unwelcome and will be treated differently.”

However, Sanders, a Christian, stood firm in her position.

Responding on Twitter, she said, “Dear @americansunited, I have received your letter and my answer is no. I will not erase the beautiful cross my kids drew in chalk on the driveway of the Governor’s Mansion or remove my post on social media, and I will not now or ever hide that I am a Christian, saved by Christ.”

“In Arkansas, we stand up to bullying liberals. We won’t let you power-wash our kids’ chalk drawings off our front steps. We won’t let you tear down Christmas decorations and stomp our tradition into the dirt. We don’t live our lives in fear of strongly worded letters coming down from Washington.”
