Rep. Charles Rangel (D-N.Y.) is already dealing with an ethics committee investigation and now faces trouble in his quest for re-election next year. Vince Morgan, a former special assistant and campaign director to Rangel, told the New York Times that Rangel "is going to have to take responsibility" for his financial dealings, which have been under scrutiny for more than a year.

"He got caught with his hand in the cookie jar," said Morgan, who hesitated to challenge Rangel. "I loved him ... He is very affable and he is a warm person, which is why I am hesitant about bad-mouthing him."

Rangel has represented the 15th District of New York -- Harlem -- since his first election in 1970. Chairman of the tax-writing Ways and Means Committee, part of the inquiry into Rangel is his failure to accurately list all of his assets on his tax returns.

Morgan worked for Rangel from 2001-2003.
