In June 2021, Massie was one of 21 House Republicans to vote against a resolution to give the Congressional Gold Medal to police officers who defended the U.S. Capitol on January 6. Also in June 2021, he was one of 14 House Republicans to vote against legislation to establish June 19, or Juneteenth (officially named "Juneteenth National Independence Day"), as a federal holiday. He said he "fully support[ed] creating a day to celebrate the abolition of slavery" but opposed its being named "Independence Day" because that would cause confusion.
