The presidency of Ronald Reagan began at noon EST on January 20, 1981, when Ronald Reagan was inaugurated as the 40th President of the United States, and ended on January 20, 1989. Reagan did not make immigration a focus of his administration, but he came to support a package of reforms sponsored by Republican Senator Alan Simpson and Democratic Congressman Romano Mazzoli, which he signed into law as the Immigration Reform and Control Act in November 1986. The bill was largely unsuccessful at halting illegal immigration, and the population of illegal immigrants rose from 5 million in 1986 to 11.1 million in 2013. Concerns about drug use prompted Congress to pass legislation such as the Comprehensive Crime Control Act of 1984 and the Anti-Drug Abuse Act of 1986, the latter of which granted $1.7 billion to fight drugs and established a mandatory minimum penalties for drug offenses.
