Chris Christie of New Jersey knew that three of his top officials were involved in a plan to shut down lanes leading to the George Washington Bridge as it was happening and that the closings were intended to punish a local mayor for declining to support him, federal prosecutors said on Monday. The assertion was an unexpected and startling beginning to the trial of two former Christie administration officials charged with closing the lanes in 2013 and then covering it up. And it was a surprising claim because of the side of the courtroom it came from, as lawyers made opening statements. Defense lawyers have long argued that Mr. Christie, a Republican, and his top advisers were well aware of the lane closings and that they directed the cover-up as they tried to protect the governor’s political aspirations — saying their clients were “thrown under the presidential bus,” as one lawyer argued on Monday. But this was the first time a prosecutor had pointed a finger at Mr. Christie. And it directly contradicts the governor’s statements in the three years since the lanes were mysteriously closed, paralyzing the borough of Fort Lee, N.J. Mr. Christie, a former top federal prosecutor in New Jersey, has consistently denied that he knew about the lane closings as they unfolded, and argued that the United States attorney’s office had “exonerated” him when it declined to indict him along with the defendants now standing trial. The prosecutor, speaking for the United States attorney’s office, said that two of the alleged co-conspirators in the case, David Wildstein and Bill Baroni, had “bragged” to the governor about the lane closings at a memorial service for the Sept. 11 terrorist attacks, on the third day of the closings, and that they had been done to “mess” with Mayor Mark Sokolich of Fort Lee, a Democrat, because he had declined entreaties to endorse the governor’s re-election. Mr. Baroni and Bridget Anne Kelly, who were close allies of Mr. Christie, are the two defendants in the trial. Mr. Wildstein and Mr. Baroni boasted to Mr. Christie that panicked phone calls from Mr. Sokolich, pleading that the lane closings were a “public safety emergency,” were deliberately being ignored, the prosecutor said. The prosecutor, Vikas Khanna, quickly moved to quell any curiosity the jury might have about why Mr. Christie was not charged in the plot. “The evidence may show that others could have, should have, perhaps known certain aspects of what was going on in Fort Lee,” he said. “Perhaps you will even wonder what happened to those people. But at the end of this case the only issue for you to decide is whether Bridget Kelly and Bill Baroni are guilty of the crimes with which they are charged beyond a reasonable doubt. That’s it.” Defense lawyers quickly seized on his comments in their own opening statements. Michael Critchley, a lawyer for Ms. Kelly, a former deputy chief of staff to Mr. Christie, said: “We know who they’re talking about. They’re talking about Governor Christie. They’re talking about Kevin O’Dowd.” (Mr. O’Dowd was the governor’s chief of staff at the time of the closings.) A spokesman for Mr. Christie, Brian Murray, responding to the prosecutor’s assertion, referred reporters on Monday to statements the governor made in 2014, in which he said he had not known about the plan to close the lanes. Mr. Murray declined to address whether the governor knew about the closings while they were happening. The office of the United States attorney, Paul J. Fishman, declined to comment on why the governor was not charged, but Mr. Fishman has said in the past that merely knowing is not a federal crime. Mr. Christie was intimately woven into the story both sides told in the packed courtroom on Monday. Prosecutors and defense lawyers alike described an administration tightly controlled by the governor, one that worked hand-in-hand with his re-election campaign to trade favors for endorsements. The governor was trying to win a big and broad margin of victory, and to win over Democratic mayors like Mr. Sokolich, so he could make the case that he was the Republican best able to win the White House. Mr. Khanna said Mr. Baroni covered up the lane closings because “this was something that was important to Trenton.” He added, “Trenton: the governor’s office.” Mr. Baroni’s lawyer, Michael Baldassare, later told the jury it would be hearing a lot about Trenton. “Trenton, Trenton, Trenton; Trenton is the governor,” he said. “Let’s make no mistake. Open a dictionary: Trenton, the governor.” The details of the plot that Mr. Khanna laid out are largely familiar by now — that Ms. Kelly sent an email in August 2013 saying “Time for some traffic problems in Fort Lee” after confirming that the mayor of that borough would not endorse Mr. Christie. A month later, two of three access lanes to the George Washington Bridge were shut down. Mr. Baroni, then the highest-ranking official at the Port Authority of New York and New Jersey, which runs the bridge, studiously ignored the mayor as he pleaded by text, email and a handwritten letter for the agency to reopen the lanes. Mr. Critchley, Ms. Kelly’s lawyer, said Mr. Christie and Gov. Andrew M. Cuomo of New York developed a strategy to cover up the lane closings as soon as they ended, and executed it through official statements over the next several weeks, lying that the closings had been a “traffic study.” Mr. Critchley characterized their strategy as one that sought not to “inflame the issue.” “The idea that they — the governors of New Jersey and New York — they’re going to let a single mother of four control the future is also crazy,” he added, referring to Ms. Kelly. A spokesman for Mr. Cuomo flatly denied that he had any involvement. “The governor did not have any role — direct or indirect — in any press statements regarding the purported traffic study,” he said.
