Q: Question: Who was the last person to retire from the US Supreme Court prior to its decision on the Gun-Free Schools act? Passage:Kohl is strongly pro-choice and opposes the death penalty. He is highly in favor of affirmative action and supports setting aside funds for women and minorities. Although he voted in favor of the 1996 Defense of Marriage Act, Kohl rejected the recent proposal to amend the U.S. Constitution to define marriage as between one man and one woman and has supported measures that ban discrimination based on sexual orientation. Kohl has consistently voted against the flag desecration amendment and in recent years has voted against restrictions on travel to Cuba and funding for TV Martí. In 2005, he secured a victory for one of his main causes: requiring handguns to be sold with child safety locks. The amendment was attached to the Protection of Lawful Commerce in Arms Act, with every Democrat and many Republicans voting in favor of the amendment. Earlier in his career, he helped push the Gun-Free Schools Act which the U.S. Supreme Court overturned in 1995 and has submitted many amendments to that effect. He is a strong supporter of public education and has rejected school vouchers. Kohl has voted in favor of allowing for the establishment of educational savings accounts.
