What they Congress need is to pass a law prohibiting any ties to lobbyist period. If a member breaks that law then they are removed from office
Congress needs to enforce its own moral instead of practicing the band of brotherhoods. They know who is guilty and refuse to to police themselves.
They also need a law for outgoing members and staff who get jobs with lobbyist and then turns around and lobby their friends who are still active in
Congress. Maybe there is a way people can start a petition to have their representative recalled from office. Will have to look in on that.
