I'm 'Out of the Loop' in Rangel Investigation, Pelosi Says

House Speaker Nancy Pelosi says she's "out of the loop" in the House ethics committee's investigation of fellow Democratic Rep. Charles Rangel.

Rangel -- a longtime New York congressman and a former chairman of the tax-writing House Ways and Means Committee -- is facing 13 counts of wrongdoing. Allegations include providing official favors in return for donations, hiding income and assets and failing to pay taxes.

Rangel said in a Tweet Sunday, "I hope that the Ethics Committee process will move forward without a rush to judgment... I really believe that I've made some difference in the Congress and I just won't stop fighting until I've had a fair and open hearing."

The statement comes after twelve Democrats have called for the embattled representative to resign.

Pelosi is sidestepping questions about Rangel's future and whether he might once again lead that powerful committee in the future.

She tells ABC television's "This Week" that it's "an elementary discussion because what we have done is to wait and see what the committee decides."
