Rep. Charlie Rangel (D-N.Y.) said that he believes a House ethics committee investigation into his personal finances and other activities is nearly complete, Dow Jones Newswire reported Friday.

The Committee on Standards of Official Conduct established an investigative subcommittee in late 2008 to examine multiple accusations of wrongdoing by Rangel, including his fundraising efforts on behalf of a City College of New York center named in his honor. The committee later expanded that inquiry to include an alleged quid pro quo of legislation for donations to the college.

In addition, the inquiry included Rangel’s ownership of a villa in the Dominican Republic and his failure to report rental income on that property, which led to unpaid taxes; Rangel’s use of House parking facilities for long-term vehicle storage; and his use of three rent-controlled apartments as his primary residence.

“I am optimistic that this very soon will be wrapped up,— Rangel told Dow Jones. “They have a sufficient amount of staff now that this will be wrapped up much sooner than later. I intend to soon be called as a witness.—

“I’m satisfied that I am being treated fairly, and am more than optimistic about the outcome,— he said.
