Your friend can apply for the TSA pre-check program to receive a Known Traveller Number. Before pre-check was created you could request a KTN if you had a common name that was on the watch list. That no longer seems to be an option. TSA will finger print you for pre-check but the KTN will clarify that your friend is not the Jan 6th rioter.
