Colorado Republican Rep. Tom Tancredo, an outspoken opponent of illegal immigration, will announce his bid for president on Monday.

Tancredo will kick off his campaign with an announcement in Iowa, where political caucuses start the presidential nominating season, an official close to the congressman said.

Tancredo has flirted with a presidential bid for more than a year and began raising money for the effort in January. After taking in more than $1 million in two months, he has decided to make his run official, said the official, who asked not to be named ahead of Tancredo's official announcement.

Tancredo's office on Friday morning said that he will make a "major announcement" Monday on a Des Moines, Iowa, radio station.
