NEW YORK, July 11 (Reuters) - Democratic presidential contender Hillary Clinton will pledge on Monday to close the carried interest tax loophole that allows private equity fund managers to pay a lower tax rate on much of their earnings, according to a draft of a speech seen by an outside adviser.

Clinton, who is seeking her party's nomination to run in the November 2016 election, took a similar stance during her last presidential campaign in 2007, and is expected to reaffirm it in a speech on her economic policy in New York City on Monday.
