NEW YORK – A rare original copy of President Abraham Lincoln's Emancipation Proclamation sold Tuesday at a New York auction for more than $2 million.

It's the second-highest price ever paid for a Lincoln-signed proclamation — after one owned by the late Sen. Robert Kennedy that went for $3.8 million two years ago.

The latest copy of the 1863 document ordering the freeing of slaves, which was auctioned at the Robert Siegel Auction Galleries, went to David Rubenstein, managing director of The Carlyle Group investment firm. The American seller remained anonymous.
