Rep. Charles B. Rangel, Democrat of New York, is being investigated by the House ethics committee for his political and fund-raising activities, reports The New York Times.

Mr. Rangel helped raise money for the City College of New York and recently helped protect a tax loophole for a major donor to the college, Eugene M. Isenberg, chief executive of Nabors Industries.

The congressman’s lawyer, Leslie Kiernan, said that Mr. Rangel’s efforts on behalf of Nabors and the other companies were unrelated to Mr. Isenberg’s financial support for the Charles B. Rangel School of Public Service at City College of New York, reports the newspaper.
