In 2002, Kohl left the Bundestag and officially retired from politics. Later, he was largely rehabilitated by his party. After taking office, Angela Merkel invited her former patron to the Chancellor's Office and Ronald Pofalla, the Secretary-General of the CDU, announced that the CDU would cooperate more closely with Kohl, "to take advantage of the experience of this great statesman". On 4 March 2004, he published the first of his memoirs, called "Memories 1930–1982", covering the period from 1930 to 1982, when he became chancellor. The second part, published on 3 November 2005, included the first half of his chancellorship (1982–90). On 28 December 2004, he was air-lifted by the Sri Lankan Air Force, after having been stranded in a hotel by the 2004 Indian Ocean earthquake. Kohl was a member of the Club of Madrid.
