President Roosevelt formally requested the declaration in his Infamy Speech, addressed to a joint session of Congress and the nation at 12:30 p.m. on December 8. The declaration was quickly brought to a vote; it passed the Senate, and then passed the House at 1:10 p.m. The vote was 82 – 0 in the Senate and 388 – 1 in the House.

Jeannette Rankin, a pacifist and the first woman elected to Congress (in 1916), cast the only vote against the declaration, eliciting hisses from some of her peers. Several colleagues requested she change her vote to make the resolution unanimous—or at least to abstain—but she refused.

"As a woman, I can't go to war," she said, "and I refuse to send anyone else." Nine other women held Congressional seats at the time. After the vote, an angry mob followed her from the Capitol building, forcing her to take refuge in a telephone booth until United States Capitol Police could rescue her.
