Captain America #275 (1982)

Steve Rogers attends an anti-nazi rally in Long Island. The demonstration is proceeding peacefully until a pro-nazi group shows up. When the violence erupts, the star-spangled avenger jumps into the mêlée to restore order. After everyone has calmed down and Captain America has spoken to the crowd, Bernie Rosenthal realizes that his voice sounds just like Steve Rogers' voice. Meanwhile, Vermin escapes from SHIELD custody. Also in this issue, Sam Wilson (aka the Falcon) announces his intentions to run for Congress.
