Vice President Joe Biden's new disclosure forms reflect the $21,000 in rent that he collected in 2011 from U.S. Secret Service.

The financial disclosure forms state that Biden collected between $15,000 and $50,000 in rent from a house in Wilmington, Del., that is worth between $100,000 and $250,000.

Biden charges $2,200 per month to live in the cottage -- which is next to his waterfront home -- according to The Washington Times, which reported last year that Secret Service agents lived at the cottage and paid rent.

"It’s a rental property so we pay rent there," a Secret Service agent told the Washington Times when asked if it was common for agents to pay rent when protecting an official.
