U.S. Sen. Ted Cruz’s office has repeatedly dismissed ethical questions about his three-times-a-week podcasting gig, saying he makes no money from the venture with a company that lobbies Congress.

But over the last year, iHeartMedia, the massive radio network that picked up the “Verdict with Ted Cruz” podcast in 2022, has made regular, and growing, payments to a super PAC supporting the Texas Republican’s reelection effort. The payments, which the media company says are associated with ad revenue from the podcast, total $630,850 — about a third of the $2 million the Truth and Courage PAC reported raising since the start of 2023, according to the latest Federal Election Commission data.
