Who is  Senator Larry Craig?

He has supported a federal constitutional amendment banning same-sex marriage, telling his colleagues that it was “important for us to stand up now and protect traditional marriage, which is under attack by a few unelected judges and litigious activists.”

In 1996, Craig also voted in favor of the Defense of Marriage Act, which denies federal recognition to same-sex marriages and prevents states from being forced to recognize the marriages of gay and lesbian couples legally performed in other states.

Craig has also opposed expanding the federal hate crimes law to cover offenses motivated by anti-gay bias and, in 1996, voted against a bill that would have outlawed employment discrimination based on sexual orientation, which failed by a single vote in the Senate.

Craig has endorsed former Massachusetts Gov. Mitt Romney in the 2008 presidential race. The senator was named in February, along with Sen. Robert Bennett of Utah, as Romney’s liaison to build support among GOP senators.

Monday night, Romney’s presidential campaign announced Craig was stepping down.
