MIAMI (AP) — A federal judge is faulting the U.S. government 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 Tuesday that the Justice Department's tactics have caused months of unnecessary delays. Altonaga said much FBI evidence released to Khan is heavily redacted and useless.

Government attorneys say they must balance national security and classified FBI material in turning over documents.

Khan claims the Justice Department knew he was innocent when he was prosecuted on charges of supporting the Pakistani Taliban. Prosecutors deny that, but the criminal case against him was dropped.

Khan's father, Muslim cleric Hafiz Khan, is serving a 25-year sentence after he was convicted in 2013.
