Protecting Political Expression Act of 2020 This bill specifies that certain offenses involving political affiliation are hate crimes. A violator is subject to criminal penalties—a prison term, a fine, or both. Further, the bill prohibits discrimination based on political affiliation in areas involving housing, federally assisted programs, and employment. The bill defines political affiliation to include, among other actions, joining, belonging to, or withdrawing from any political party, political action committee, or super political action committee.
