Craig represented Idaho in Congress for more than a quarter-century, including 17 years in the Senate. He was up for re-election next year.
Republicans, worried about the scandal's effect on next year's election, suffered a further setback Friday when veteran Republican Sen. John Warner of Virginia announced he will retire rather than seek a sixth term. Democrats captured Virginia's other Senate seat from the GOP in the 2006 election.
Craig opposes gay marriage and has a strong record against gay rights. He was a leading voice in the Senate on gun issues and Western lands. Craig chaired the Senate Veterans Affairs Committee and was a senior member of the Appropriations Committee, where he was adept at securing federal money for Idaho projects.
A fiscal and social conservative, Craig sometimes broke with his party, notably on immigration, where he pushed changes that many in his party said offered "amnesty" to illegal immigrants. Much of the impetus behind Craig's push to ease bureaucratic hurdles to immigrant farm workers stemmed from his background as a rancher and the state's large rural, farming community.
