(CNN) -- She's been in the national spotlight only a few years, but in that fairly short amount of time, Michele Bachmann has gained real notoriety -- even if, at times, the attention has come for reasons that she may wish to put behind her.

A third-term congresswoman representing Minnesota's 6th District, Bachmann announced during a CNN GOP presidential debate Monday night that she had filed paperwork to enter the presidential race.

She said she plans to make a formal announcement of her candidacy "soon."
