Rangel once chaired the Ways and Means Committee, which writes tax laws. But now, the House Ethics Committee charges that he hid thousands of dollars in rental income which was not taxed.
Rangel faces over a dozen ethics charges and eight House members will decide if he's guilty. One of the eight is Democrat Congressman G. K. Butterfield of Wilson.
Republican Ashley Woolard is challenging Butterfield in the November election. Woolard says Butterfield should return $4,000 in campaign contributions Butterfield received from Rangel in 2004 and 2008.
"Justice Butterfield, when he was a judge, would have never tried a case that he took money from somebody that he was getting ready to judge," said Woolard. "Regardless of when he received the money, he is still beholden to Charlie Rangel. He needs to give the money back immediately, and in addition resign the Ethics Committee effective immediately."
Congressman Brad Miller says he sat with Butterfield before on an ethics panel which admonished Rangel for corporate funded plane flights to the Caribbean.
"What I saw in Congressman Butterfield in that experience was a fidelity to the rules," said Miller.
Butterfield did not return phone calls Tuesday.
