Trump rally chants "lock her up" after explosive device sent to Clinton

President Trump’s supporters chanted “lock her up” ahead of his arrival at a rally in Mosinee, Wis., on Wednesday evening, just hours after the Secret Service said it found “potential explosive devices” in mail sent to former Secretary of State Hillary Clinton at her home in Chappaqua, New York.

Video of the rally showed the crowd chanting the phrase as Sen. Leah Vukmir (R) delivered remarks shortly before Trump’s scheduled appearance.
