Multiple reliable sources confirm that Vice President Kamala Harris and Minnesota Governor Tim Walz sat for their first joint interview with CNN’s Dana Bash, airing as a primetime special on Thursday, August 29, 2024, at 9 p.m. ET.

• CNN’s own press release announced “THE FIRST INTERVIEW: HARRIS & WALZ – A CNN EXCLUSIVE” with Dana Bash, scheduled for Thursday, August 29 at 9 p.m. ET. (cnnpressroom.blogs.cnn.com)
• Coverage from NPR and affiliated outlets notes that Harris, joined by Walz, sat down with CNN’s Dana Bash in Savannah, Georgia, describing it explicitly as this first sit‑down interview as the Democratic nominee, dated August 29, 2024. (news.wjct.org)
• A Reuters fact‑check further confirms that the full 27‑minute Harris–Walz interview with CNN’s Dana Bash aired as scheduled on August 29 at 9 p.m. ET. (reuters.com)

Given that the podcast was released Friday, August 30, 2024, Jason’s prediction that “Kamala and [Walz] will do an interview with Dana Bash tonight, the night we’re taping this on Thursday” matches what actually happened the preceding Thursday night (August 29, 2024). Therefore, the prediction is right.
