In foreign policy, Clinton ordered U.S. military intervention in the Bosnian and Kosovo wars, signed the Iraq Liberation Act in opposition to Saddam Hussein, participated in the 2000 Camp David Summit to advance the Israeli–Palestinian peace process, and assisted the Northern Ireland peace process. In 1998, Clinton was impeached by the House of Representatives, becoming the second U.S. president to be impeached, after Andrew Johnson. Clinton presented himself both as a moderate and as a member of the New Democrat wing of the Democratic Party, and he headed the moderate Democratic Leadership Council in 1990 and 1991.
