Clinton was inaugurated as the 42nd president of the United States on January 20, 1993. Less than a month after taking office, he signed the Family and Medical Leave Act of 1993, which required large employers to allow employees to take unpaid leave for pregnancy or a serious medical condition. This action had bipartisan support, and was popular with the public. Two days after taking office, on January 22, 1993—the 20th anniversary of the U.S. Supreme Court decision in Roe v. Wade—Clinton reversed restrictions on domestic and international family planning programs that had been imposed by Reagan and Bush. Clinton said abortion should be kept 'safe, legal, and rare'—a slogan that had been suggested by University of California, San Diego political scientist Samuel L. Popkin and first used by Clinton in December 1991, while campaigning. During the eight years of the Clinton administration, the U.S. abortion rate declined by about 18.4 percent.
