A group of Vice President Kamala Harris’s supporters released their first media spot on Wednesday in an effort to win over Christian voters who are lukewarm on former President Donald Trump’s campaign.

Evangelicals for Harris, a 501(c)(4) organization associated with Faith Voters, released a new ad that featured remarks from an interview between GOP pollster Frank Luntz and Trump before he was a candidate in the presidential race in 2015 at the Family Leadership Summit in Iowa. During that conversation, Trump talked about his Christian faith but said he never sought forgiveness for his sins, in response to a question from Luntz.
