U.S. congresswoman Michele Bachmann on Wednesday ended her campaign to become the 2012 Republican U.S. presidential candidate and called on supporters to rally behind the party's eventual nominee.

Bachmann did not say whether she would make an endorsement.

I have decided to stand aside. I will not be continuing in the race for the presidency, Bachmann told a news conference in Des Moine, Iowa.

The announcement came a day after she received only 5 percent of the vote in the Iowa nominating caucuses, dealing what many saw as a fatal blow to her presidential ambitions.
