What is the % of congressmen who have current passports. I'm doing
research on congressmen and their lack of travelling and understanding
of other cultures and therefore have narrow perspectives.

Hello,

According to Rep. Gil Gutknecht, fewer than one-third of members of
Congress have passports. (1)
