On, Clark becomes a pawn in Czech billionaire and Kealty supporter Paul Laska's vendetta to discredit Ryan during the presidential campaign. The Emir had identified him as one of his captors to his Laska-affiliated lawyer. When it was revealed that he killed an East German Stasi operative in Berlin in 1981 (which was not a CIA matter but a personal job by his friend and Berlin station chief who had been blackmailed), he becomes the subject of a manhunt by the FBI and later French investigators hired by Laska. Clark goes on the run and travels to eastern Europe to clear his name, later finding out that rogue SVR operative Valentin Kovalenko had given the information to Laska, who in turn covertly presented it to Kealty. However, he is captured shortly after and later tortured for information about The Campus by Kovalenko's men. He is later rescued by the Russian government, who then assigns him to temporarily lead Rainbow in order to retake a Russian spaceport which had been hijacked by Muslim Dagestani terrorists intent on launching nuclear weapons into Moscow. In Threat Vector, Clark has been exonerated by the outgoing Kealty administration. After an assassination job on a cell of former Libyan intelligence officers in Istanbul, he briefly retires from The Campus due to old age. However, he later comes out of retirement when Chinese special operations forces attack the headquarters of The Campus. He travels to China with fellow Campus operatives and works with the local rebels and FSB to assassinate People's Liberation Army Chairman Su Ke Qiang, who has been waging war against the United States by trying to annex Hong Kong, Macau, Taiwan, and territories in the South China Sea by military force as well as sanctioning cyberattacks on the U.S. In Command Authority, Clark becomes director of operations for The Campus. He travels to Ukraine along with his fellow operatives to gather intelligence on Russian criminal organization Seven Strong Men and its leader Gleb the Scar. They take part in defending a CIA special mission compound in Sevastopol, which came under attack from pro-Russian protesters aided by FSB proxy agents and the Seven Strong Men. Clark later cooperates with Delta Force operatives in capturing Gleb the Scar, revealed to be directly involved in the polonium poisoning of former SVR head Sergey Golovko, in his heavily-guarded base of operations in Kyiv.
