DART suspends driver after she refuses to use bus bearing atheist ad
Controversy over a bus advertisement promoting a local atheist group has found its way to the driver’s seat.
On Monday, the Des Moines Area Regional Transit Authority suspended bus operator Angela Shiel after she refused to drive a bus with an Iowa Atheists and Freethinkers ad on its side. Shiel, 41, said the ad’s message, “Don’t believe in God? You are not alone,” went against her Christian faith.
