One of the viewers who wasn’t too happy to see Bad Bunny’s performance at Sunday’s Grammys captioned with “Singing Non-english” was U.S. Rep. Robert Garcia (D-Long Beach), who apparently reached out to CBS President & CEO George Cheeks wanting an explanation for the blunder.

Viewers griped on social media that the closed captions did not translate what the artist was singing or saying. All they saw were the three words Speaking Non-english, so those who did not speak Spanish could not understand what Bad Bunny sang or what he said when he won the Grammy in the Best Música Urbana Album category.

In response to the backlash, CBS ended up adding Spanish language closed captioning to replays of Bad Bunny’s Grammy performances. Cheeks, meanwhile, responded to an inquiry by Garcia. The letter is below.

Dear Representative Garcia:

Thank you for your letter and sharing your feedback about the Grammy Awards.
