NEW YORK (CNN/Money) - Wall Street telecommunications analyst Jack Grubman donated $100,000 to the Democratic Senatorial Campaign Committee just days before news broke of the WorldCom Inc. accounting scandal, committee officials told CNN/Money Wednesday.

Grubman, a former star analyst at Salomon Smith Barney Inc., has come under fire and stocks of companies he formerly covered have been hammered. He sent the check on June 23, the DSCC said, confirming earlier press reports, two days before WorldCom disclosed that it hid $3.8 billion in expenses, possibly making it the biggest corporate fraud in history.

The news comes as congressional committees investigating WorldCom examine Grubman's dealings with the company. Grubman has said he sat in on at least two board meetings, almost unheard-of access for an analyst, according to the report. Lawmakers also are looking into whether Grubman's bullish outlook on WorldCom and other companies was tied to hefty fees paid to Salomon for investment banking services.

The DSCC received Grubman's donation, his biggest political contribution ever, on June 27, the same day he was subpoenaed by the House Financial Services Committee, and one day after the Securities and Exchange Commission filed a civil fraud suit against WorldCom, the Wall Street Journal reported.

The telecom filed for bankruptcy court protection last month after it lost the ability to raise cash.

Grubman's donation was so-called soft money, which can be raised in unlimited amounts for party building and get-out-the-vote efforts. New campaign finance legislation signed into law earlier this year will ban such soft-money contributions starting in November.
