Ronald Reagan
Reagan originally did not support making Martin Luther King Jr.'s birthday a national holiday, because of cost concerns. But on November 2, 1983, Reagan signed a bill to create a federal holiday honoring King. The bill had passed the Senate by a count of 78 to 22 and the House of Representatives by 338 to 90. The holiday was observed for the first time on January 20, 1986. It is observed on the third Monday of January.
