Jon Huntsman ended his campaign for president Monday on a cautionary note to fellow Republicans, urging them to abandon negative campaigning or risk fostering a "toxic" political environment.

Huntsman backed  former Massachusetts Gov. Mitt Romney, "despite our differences and the space between us on some of the issues."

Huntsman's campaign launched with a great deal of media fanfare, not least of which resulted from his decision to resign a spot in the Obama administration to run against a president for whom Huntsman had worked.
