WASHINGTON (AP) -- Democratic Sen. Tim Kaine of Virginia says he'll endorse Hillary Rodham Clinton for president if the former secretary of state decides to seek the Democratic nomination in 2016.
The Associated Press has obtained a copy of remarks Kaine is preparing to deliver at a breakfast Saturday in Columbia, South Carolina.
In the remarks, Kaine says Clinton is a "classic American optimist" who can lead the U.S. "in a very complicated world."
The endorsement is the latest sign of support for Clinton. She leads all Democrats in early presidential polls even though she has yet to declare whether she will undertake another campaign for the White House.
Kaine was an early supporter of Barack Obama in the 2008 Democratic primaries when Obama challenged Clinton for the nomination.
