Things are heating up for ole Dollar Bill:

“NEW ORLEANS — An aide to U.S. Rep. William Jefferson, a congressman who allegedly stashed $90,000 in bribe money in his freezer, has been subpoenaed by a federal grand jury in Virginia investigating Jefferson’s African business dealings.

Despite the probe hanging over him, Jefferson, D-La., won re-election last December to his ninth term to represent a district that covers most of New Orleans.

This would be the second time the grand jury has asked Stephanie Butler, Jefferson’s district manager, to appear. She was among six of Jefferson’s staff members subpoenaed in March 2006 by the grand jury. She could not be reached for comment Wednesday.

Remi Braden-Cooper, Jefferson’s spokeswoman, said the subpoena was announced on the House floor Wednesday, which she said is a customary procedure for House staff. Braden-Cooper declined to discuss the probe, adding that “nobody’s releasing any information about the case” because it is still before the grand jury.

The U.S. attorney’s office in Virginia did not immediately return a telephone call seeking comment.”

Here’s the comment, she’s singing loudly.
