To boost his profile, Zuberi also donated to, or hired, several Washington advocacy groups, lobbying shops and public relations firms. Those officials included Olson, former NATO supreme commander Gen. Wesley Clark and former acting director of U.S. Immigration and Customs Enforcement John Sandweg. The trio lobbied U.S. officials after returning from their Doha meeting with Qatari officials, the FBI said. He added that one of his greatest regrets was recruiting Allen into the effort because of the subsequent negative publicity. Allen has denied any wrongdoing but stepped down as president of the Brookings Institution, a prestigious Washington think tank, amid the FBI investigation.
