MANCHESTER, United States -- US Congresswoman Michelle Bachmann on Monday night said on the first Republican primary debate she had filed paperwork to run for President.

Bachmann, a congress member from Minnesota, is a favorite of the Tea Party movement. She joins a muddled GOP field which includes front runner Mitt Romney, former House of Representatives Speaker Newt Gingrich, Texas Congressman Ron Paul, former Minnesota Governor Tim Pawlenty and former Pennsylvania Senator Rick Santorum. All of them are on stage of the debate held at Saint Anselm College in Manchester, New Hampshire.

Former Ambassador to China Jon Huntsman is also expected to announce his bid for president later this month.
