When the journalist inquired about the identity of the member, a congressional aide refused to say.
The mystery was solved when Robert Garcia, a Democrat from Long Beach, California, tweeted that he was the person who would be sworn in on the comic book.
"Will be proudly sworn-in to Congress on the U.S. Constitution. Underneath the Constitution will be 3 items that mean a lot to me personally," Garcia tweeted.
"A photo of my parents who I lost to covid, my citizenship certificate & an original Superman #1 from the @librarycongress," he added. Garcia has described himself as a comic book nerd.
Garcia is the first openly LGBTQ immigrant to be voted into the U.S. Congress. He was formerly the mayor of Long Beach from 2014 until he was elected for the 42nd district of California.
Both of his parents died from coronavirus complications in 2020. He and his family members immigrated to the U.S. from Lima, Peru, when he was 5 years old.
The comic book was first published in 1939, when it was sold for ten cents a copy. In 2022, a copy of that book sold for $5.3 million according to CGC, a grading company for comics.
"Superman #1" is not, however, the first appearance of the superhero in comics. That distinction belongs to "Action Comics #1," which was published in 1938. A copy of that comic book sold for $3.18 million in 2021.
Garcia says he plans to display various comic book images in his congressional office.
