Congressman Jefferson looks to be sitting pretty, according to Roll Call:

House Democratic leaders are not expected to pressure embattled Rep. William Jefferson (D-La.) to forfeit his lone remaining committee assignment, even as two Republican lawmakers who similarly face intense FBI scrutiny have relinquished their posts in recent days.
Democratic sources indicated that Speaker Nancy Pelosi (D-Calif.) is unlikely to ask the Louisiana lawmaker, who is under federal investigation, to give up his seat on the Small Business Committee.
