According to Above the Law, Foo Fighters frontman Dave Grohl dedicated the song 'My Hero' to special counsel Jack Smith during a recent concert. The outlet also reports that Grohl wore an Iowa Hawkeyes shirt, a detail it describes as 'really twist[ing] the knife.'
The post adds that Smith has never been to a Hawkeyes game, but he will go to a Foo Fighters show. The exact context of the dedication and the shirt's significance are not detailed in the report.
Because this is a single source, the broader meaning of the gesture is unclear. The article appears to treat the moment as a notable cultural reference in the legal world, but no further explanation is provided.
