What does "defendant has not been held accountable.” (4th paragraph) mean?

Context>>>>>>>>>>
The president has broad power to issue pardons for federal crimes, but has no such authority in state cases.

While Mr. Trump has not said he intends to pardon his former campaign chairman, he has often spoken of his power to pardon and has defended Mr. Manafort on a number of occasions, calling him a “brave man.”

The new state charges against Mr. Manafort are contained in a 16-count indictment that alleges a yearlong scheme in which he falsified business records to obtain millions of dollars in loans, Mr. Vance said in a news release after the federal sentencing.

“No one is beyond the law in New York,” he said, adding that the investigation by the prosecutors in his office had “yielded serious criminal charges for which the defendant has not been held accountable.”

The indictment grew out of an investigation that began in 2017, when the Manhattan prosecutors began examining loans Mr. Manafort received from two banks.
