snip-"WASHINGTON (AP) President Joe Biden is inviting thousands to celebrate at the White House on Tuesday as he signs into law gay marriage legislation before a bipartisan crowd that reflects growing acceptance of same-sex unions."
snip-"Lawmakers from both parties will be there, as will first lady Jill Biden and Vice President Kamala Harris and her husband, Doug Emhoff. The White House promised musical performances but was trying to maintain suspense about the headliners."
snip-"The new law is intended to safeguard gay marriages if the U.S. Supreme Court ever reverses Obergefell v. Hodges, its 2015 decision legalizing same-sex unions nationwide. The new law also protects interracial marriages. In 1967, the Supreme Court in Loving v. Virginia struck down laws in 16 states barring interracial marriage."
