Rangel wasThursday after his attorneys and lawyers for the House panel investigating the former Ways and Means Committee chairman failed to negotiate a settlement. On Friday, the panel's chairwoman said it would by the full House.
The president noted that given Rangel's age, 80, he's at the end of his career anyway.
"I think Charlie Rangel served a very long time and served his constituents very well, but these allegations are very troubling, and, you know, he's somebody who is at the end of his career, 80 years old," Mr. Obama said. "I'm sure that what he wants is to be able to end his career with dignity, and my hope is that happens."
Rangel is running for his 21st term in House. If he wins his Sept. 14 primary contest, he is expected to easily win the general election in his heavily Democratic district.
