The FBI took Raez Qadir Khan, 48, of Portland into custody on charges of providing material support for a reputed terrorist who was killed in the suicide bombing of the Inter-Services Intelligence headquarters in Lahore May 27, 2009.
The blast killed 30 people and injured about 300.
An indictment unsealed at Khan's initial court appearance in Portland accused the naturalized U.S. citizen of having a relationship with Ali Jaleel, a Maldivian national who perished in the Lahore bombing.
The indictment accused Khan of sending Jaleel money so he could travel to Pakistan to join up with radical jihadists, and of giving Jaleel advice on avoiding detection by the authorities. He also allegedly wired money to Jaleel inside Pakistan and promised he would help take care of Jaleel's family in the Maldives.
Shortly after the bombing, al-Qaida released a video in which Jaleel claimed credit for the attack, the U.S. attorney's office said in a written statement.
Khan, who faces life in prison if convicted, was ordered to appear for a detention hearing Wednesday.
