Prosecuting former state Sen. Thomas L. Bromwell - charged last week with steering millions of dollars in building contracts to a single construction firm - could be the first major test for Maryland's new U.S. attorney.

Rod J. Rosenstein, who took the post as the state's top federal prosecutor last summer, proclaimed that terrorism would be his first priority. But his office of 70 attorneys also has been trying to regain its footing in public corruption cases since former U.S. Attorney Thomas M. DiBiagio resigned in December.

Lawyers in and out of his office called for DiBiagio's ouster after he wrote a memo to his staff, pushing for three "front page" public corruption indictments by the fall election. Bromwell's attorney charged that last week's indictment is one of those three cases.

Now legal watchers wonder what lingering impact that memo will have on the case against Bromwell, once one of the most powerful figures in Annapolis.

"There is no question that if I'm on the defense team, I'm going to want the jury to question the motives of the prosecution," Professor Byron Warnken of the University of Baltimore School of Law said. "The cycle of cases is so long that they could say that this is one of the cases in the memo."

DiBiagio oversaw the successful prosecution of pension fund manager Nathan Chapman on stock fraud charges and gained notice for the conviction of Edward T. Norris, Baltimore's former police commissioner who pleaded guilty to conspiring to misuse a department fund.

When DiBiagio's controversial memo became public in the summer of 2004, the Department of Justice ordered that officials in Washington would need to approve any future public corruption indictments out of Maryland. DiBiagio's interim replacement dropped two corruption cases that DiBiagio had shepherded through the system.

Last week, a federal grand jury indicted Bromwell, a Democrat; his wife, Mary Pat; and W. David Stoffregen, the former president of Poole and Kent Co., a large plumbing and steam-fitting contractor based in Baltimore.

Yesterday, David M. Jackman, a project manager for Poole and Kent, was charged with making a false statement to the FBI about discounted work done by the company at Bromwell's Baltimore County home.

The case could provide a window into how large public and private construction projects in the Baltimore area can be fixed by politicians.

The Bromwells will make their first appearance in U.S. District Court in Baltimore on Monday, prosecutors announced yesterday. Two days later, Stoffregen is scheduled to appear in court.

According to the indictment, the Bromwells are accused of taking almost $300,000 from Stoffregen over five years in the form of discounted home construction work and a salary to Mary Pat Bromwell for a no-show job at Namco, a "front" company that posed as a female-owned subcontractor. It was really operated by Poole and Kent, prosecutors charge.

In return, according to the court papers, Thomas Bromwell intervened on behalf of Poole and Kent in contract negotiations for work at a state juvenile detention center and elsewhere, according to the indictment.

Bromwell is also accused of pressuring high-ranking officials at the University of Maryland Medical System to bypass the lowest bid on a job and award a $13 million contract to Poole and Kent.

The Bromwells and Stoffregen, through their attorneys, maintain their innocence.

So far, many officials in Annapolis have expressed sympathy for Bromwell, who also has the backing of his employer. He will be able to keep his job as president and chief executive officer of Maryland Injured Workers' Insurance Fund, the chairman of the board announced last week.

"We are confident that he is fully capable and ready to discharge his executive duties as the legal process takes its course. We believe in his innocence, and wish him complete success in his defense against these charges," said Daniel E. McKew, who oversees the state's largest workers' compensation insurance carrier, a quasi-public agency with $1.3 billion in assets and reserves.

Bromwell's salary, bonuses and car allowance make his post worth about $250,000 a year. The fund's board is appointed by the governor.

To pursue the former state senator, federal investigators cast a wide net, convening grand juries for years in an attempt to gather evidence against him.
