WASHINGTON  - Three US senators John McCain, Joseph Lieberman and Mark Kirk on Thursday demanded of Pakistan to prevent the judicial commission investigating former ambassador Husain Haqqani and save him from becoming a political tool for revenge.

In a joint press statement, the senators expressed reservations on the treatment of former Husain Haqqani. They said they were “increasingly troubled by Ambassador Haqqani’s treatment since he returned home to Pakistan, including the travel ban imposed on him. Like many in Washington, we are closely following Ambassador Haqqani’s case.” According to the press release, the senators urged Pakistani authorities to resolve the matter swiftly. The senators said the former ambassador had served his country honourably in his role as a diplomat. “While we did not always agree with Ambassador Haqqani, and our exchange of views could be different at times, we always had the highest respect for him and knew he was serving his nation and the government with patriotism and distinction. We regret that the Pakistani people have lost a tough-minded, eloquent, and principled advocate for their nation’s interests now that Ambassador Haqqani has departed Washington.”

The press release further stated that the Pakistani people “can be proud of the service that Ambassador Haqqani.”

 has provided to Pakistan, and we look forward to the day when he can once again serve the government and people of Pakistan as one of the nation’s finest leaders.” In a related development, sources said the former ambassador’s wife and presidential spokesperson Farahnaz Ispahani who had accompanied president Zardari during his treatment in Dubai, had proceeded to Washington to muster support for her beleaguered spouse.
