Missouri Sen. Claire McCaskill, who famously backed Barack Obama early in Obama's presidential campaign over Hillary Clinton, today more or less endorsed Clinton for president on her last day as secretary of state.

“Hillary has earned the respect and admiration of people in every nation across the globe," McCaskill said in a statement. "Americans are rightfully proud of her leadership through volatile situations abroad, and her lifetime of tremendous service to this country.

"I know that Hillary will succeed in whatever comes next for her—and if her future plans include seeking the Presidency, which I hope they do, then I look forward to being on her team and working my heart out to see her elected.”
