Washington (CNN) - Embattled Rep. Charlie Rangel, D-New York, walked out of his House ethics subcommittee hearing Monday morning, complaining that he has not had sufficient time to hire a new legal team to respond to corruption allegations.
The subcommittee members continued meeting behind closed doors.
"Fifty years of public service is on the line. And I truly believe that I am not being treated fairly," he declared. "I deserve a lawyer."
Rangel told the subcommittee he has already spent $2 million defending himself from the charges, and had been advised the hearing - similar to a trial - could cost him another $1 million.
He complained that he was not being given enough time to raise funds to hire new lawyers because the committee was rushing to complete its work before the conclusion of the current lame duck Congress.
Rangel's original defense team left him in September.
"What theory of fairness would dictate that I be denied due process ... because it is going to be the end of this session?" he asked.
Ethics committee chair Rep. Zoe Lofgren, D-California, replied that it was Rangel's responsibility to assemble his legal team.
"Retention of counsel is up to the respondent," she said.
Rangel, who has served in the U.S. House of Representatives since the 1970s, stepped down as Ways and Means Committee chairman after a slew of ethics allegations. Rangel faces 13 allegations, include failing to pay taxes on a home in the Dominican Republic, misuse of a rent-controlled apartment for political purposes and improper use of government mail service and letterhead.
House Republicans and some House Democrats have called for Rangel to resign because of the alleged ethics violations.
In August, Rangel said nothing "will stop me from clearing my name from these vile and vicious charges."
Rangel also offered explanations for the ethics charges against him, characterizing them as mistakes and acknowledging violations of House rules but denying they amounted to corruption.
"It's not corrupt," he said when responding to assertions that he used House letterhead to approach possible contributors to a university policy center in his name. "It may be stupid. It may be negligent, but it's not corrupt."
Regarding an accusation that he used a rent-controlled apartment as a campaign office, Rangel has said he did nothing wrong but was "insensitive to the appearance of being treated differently."
"I plead guilty of not being sensitive," he said.
Democratic Rep. Maxine Waters of California is also scheduled to have an adjudication hearing with the House ethics committee this month, on November 29. Waters has denied the allegations against her, which include steering federal bailout money to Massachusetts-based OneUnited Bank - in which her husband had a financial stake.
