A federal judge sternly blamed the U.S. government Tuesday for lengthy delays in a lawsuit filed by a Pakistani-American man accusing the U.S. of malicious prosecution in a terror-financing case.

U.S. District Judge Cecilia M. Altonaga agreed with Irfan Khan’s lawyer that the Justice Department’s tactics have caused months of unnecessary delays. Altonaga said much FBI evidence released about its investigation into Khan’s alleged ties to the Pakistani Taliban is heavily redacted and useless.
