"I wish her the best of luck," Sanders told TMZ Sports while crossing the street in Washington. "Get strong, get tough and win."
Rousey, a fan favorite, lost her Ultimate Fighting Championship bantamweight title to Holly Holm on Nov. 14 in a major upset. Rousey had previously been undefeated.
Rousey said in a Nov. 10 interview with Maxim that she plans to vote for Sanders, "because he doesn't take any corporate money." If Sanders loses in the Democratic primary, Rousey said she will vote for a third-party candidate as she has done in the past.
