(CNN) - Republican Rep. Paul Ryan of Wisconsin announced Monday that he will not run for the GOP presidential nomination in 2012.
Ryan said he appreciates the support of those who encouraged him to launch a bid for the White House, but that he will continue to serve in Congress.
"While humbled by the encouragement, I have not changed my mind, and therefore I am not seeking our party's nomination for President," Ryan said in a statement. "I remain hopeful that our party will nominate a candidate committed to a pro-growth agenda of reform that restores the promise and prosperity of our exceptional nation. I remain grateful to those I serve in Southern Wisconsin for the unique opportunity to advance this effort in Congress."
