In a brief letter to the chairman and ranking member of the House Ethics Committee, Pelosi wrote that an investigation by the bipartisan panel “to determine if the Rules of the House of Representatives have been violated is warranted.”

The letter comes after Pelosi and Democratic Congressional Campaign Committee Chairman Steve Israel (N.Y.) said Sunday night that they would seek investigations into Wu, who faces allegations by a young woman of sexual misconduct.

Wu released a statement Saturday regarding the alleged incident, calling the situation “very serious” but making no mention of his own actions.

“I have absolutely no desire to bring unwanted publicity, attention, or stress to a young woman and her family,” Wu said.

In the days since the news of the allegations against Wu surfaced, multiple outlets have reported that the seven-term Democrat will not seek reelection in 2012.

Pelosi’s full statement to the ethics committee is below.

Dear Chairman Bonner and Ranking Member Sanchez:

Recent press reports and statements attributed to our colleague, Representative David Wu, indicate that he may have engaged in inappropriate activities.

An investigation by the Ethics Committee to determine if the Rules of the House of Representatives have been violated is warranted.
