Lanny A. Breuer, the federal prosecutor who led the Justice Department’s response to corporate crime in the wake of the financial crisis, announced on Wednesday that he is stepping down after nearly four years in the post.
As head of the Justice Department’s criminal division, one of the most senior roles at the agency, Mr. Breuer tackled corporate bribery and public corruption. But it was his focus on Wall Street that received the most attention, from supporters and critics alike.
While he has come under fire for a dearth of prosecutions on Wall Street in response to the crisis, Mr. Breuer also oversaw an aggressive crackdown on money-laundering and interest-rate manipulation at some of the world’s biggest banks. In two weeks last month, he joined a nearly $2 billion case against HSBC for money-laundering and a $1.5 billion settlement with UBS for rate-rigging. Next week, he is expected to take a similar rate-rigging action against the Royal Bank of Scotland.
“I think the criminal division is a fundamentally different place than it was four years ago,” Mr. Breuer said in an interview on Tuesday. “It’s the highlight of my professional career.”
His departure, effective March 1, was widely expected. Mr. Breuer had told friends for weeks that he was ready to leave the public sector. While he has not announced his next step, it is expected that he will return to private practice. He was previously a partner at Covington & Burling, a white-shoe law firm.
By virtue of his perch at the Justice Department in Washington, Mr. Breuer became the face of Wall Street prosecutions in the aftermath of the financial crisis. But when few such cases materialized, critics like the Occupy Wall Street protesters turned on him, portraying him as an apologist for banks at the center of the mortgage mess.
In contrast, he drew praise for the sweeping crackdown on rate-rigging in the banking industry, which has largely involved international benchmark rates.
In a rate manipulation case last month, Mr. Breuer’s team secured a major payout from UBS and a guilty plea from the bank’s Japanese unit, making UBS the first big global bank in more than two decades to have a subsidiary plead guilty to fraud. Mr. Breuer, who announced the action after rejecting a last-minute plea from the bank’s chairman, also filed criminal charges against two former employees at the bank.
The deal sent a strong signal that the authorities wanted to hold banks responsible for their wrongdoing.
Following the UBS model, the Justice Department is now pursuing a guilty plea from a Royal Bank of Scotland subsidiary in Asia over its role in the interest rate manipulation scandal, people briefed on the matter said. That settlement, which could come as soon as next week, is likely to include more than $650 million in fines imposed by American and British authorities, two other people with direct knowledge of the matter said.
In an interview, Mr. Breuer said the rate-rigging case amounted to “egregious criminal conduct.” He struck a similar tone about two other major financial cases — the convictions of executives from Taylor, Bean & Whitaker, a now-defunct mortgage lender, and the 110-year prison term imposed on R. Allen Stanford for his Ponzi scheme.
Mr. Breuer has also focused on money-laundering, creating a task force in 2010 that has levied more than $3 billion in fines from banks, including the record fine against HSBC. He stopped short of indicting HSBC after some regulators warned that doing so could destabilize the global financial system.
Mr. Breuer argued that the charges he did not bring — for example, against Goldman Sachs and other banks suspected of fraud after selling toxic mortgage securities to investors — could not have been proved. It was not for a lack of trying, he said, noting that United States attorneys across the country, after reviewing the same evidence he did, also declined to act.
“It’s important for me to hold the financial institutions accountable,” he said. “There’s never been a time that a prosecutor said we should bring a securitization case and I said no.”
Under Mr. Breuer, the division has also increasingly used a 1977 law, the Foreign Corrupt Practices Act, to prosecute corporate bribery.
He also helped run the Justice Department’s investigation of the BP oil spill in the Gulf of Mexico, resulting in the company paying $4.5 billion in fines and other penalties and pleading guilty to 14 criminal charges related to the rig explosion in 2010.
In a statement, Attorney General Eric H. Holder Jr. praised Mr. Breuer. “Lanny has led one of the most successful and aggressive criminal divisions in the history of the Department of Justice,” he said.
Mr. Holder stood behind Mr. Breuer when questions arose about his involvement in the botched gun-trafficking case known as Operation Fast and Furious. The pair, who were both largely cleared after an inspector general investigation, worked together at Covington.
For years, Mr. Breuer moved in and out of government. The son of Holocaust survivors who fled Europe and settled in Queens, he landed at the Manhattan district attorney’s office after graduating from Columbia Law School. In between stints at Covington, he worked as a White House special counsel, defending President Bill Clinton amid federal investigations and impeachment proceedings.
In the interview on Tuesday, Mr. Breuer reflected on his unusual path to the Justice Department.
“The fact that I got to go from Elmhurst, Queens, to the criminal division is remarkable,” he said.
