Rep. Charlie Rangel, D-N.Y., said he's ready to fight the series of ethical allegations against him.

A House investigative committee charged the New York Democrat with multiple ethics violations July 22. He will now go before a bi-partisan panel next week for a public hearing.

"I've looked forward for over two years to asking them to look at this and throw out what I believe has no substance," Rangel said.

"I don't have any fear at all -- politically or personally -- what they come up with," he later added.

Among other things, Rangel faces questions of how he bought four New York apartments below market value.

He's also accused of hiding an investment account worth $500,000 and failing to report income or pay taxes on a villa he owns in the Dominican Republic.

Rangel has served in Congress for 40 years and remains popular in his home district of Harlem where he is running for re-election in the Fall.
