Schwarzenegger, Medvedev hang out in Moscow

During an official trade mission to Russia this week, California Gov. Arnold Schwarzenegger (R) noted on Twitter that he's also spent time with friend and Russian president Dmitry Medvedev.

"Having a great time with President Medvedev in his beautiful residence," Schwarzenegger tweeted Monday.

He later posted a photo of one of Medvedev's cars — a vintage "Chaika" luxury sedan manufactured by the Soviets in the 1950s.

"Riding with President Medvedev in his great car. You're a great driver, Mr. President!" he said.

Medvedev then took Schwarzenegger — a former body builder — to his gym.

"I discussed with @Schwarzenegger not only investment but also sports," he quipped. "My mornings always start at this gym."

"Thx 4 good time training," Schwarzenegger tweeted later.
