The findings were submitted to Pakistan's Supreme Court Tuesday after months of hearings, The New York Times reported.
The commission said Haqqani sent a memo to Adm. Mike Mullen, then chairman of the Joint Chiefs of Staff, in May 2011 after the death of Osama bin Laden, seeking U.S. help to avert a possible coup.
Haqqani denies any link to the memo and says he is being hounded for the perception that he is pro-American. He said he will challenge the report, which he alleges the commission is using to distract from corruption allegations against the son of the chief justice, the newspaper said.
