A nonprofit issues group is labeling James Comey a political “showboat” in a television ad set to air Thursday, the day the former FBI director testifies on Capitol Hill.

Comey “put politics over protecting America,” a narrator says in the 30-second spot, titled “Showboat,” which was shared with The Associated Press. It accuses him of being “consumed with election meddling” even as “terror attacks were on the rise.”

Great America Alliance has paid for the ad, which is slated to run digitally Wednesday and appear the next day on CNN and Fox News. The group, formed after President Donald Trump’s election to advocate for his administration, is not required to disclose its donors.
