Don’t worry, Newt, she’s not a witch.

(ABC News) — Christine O’Donnell, the former Republican Senate candidate and a tea party favorite during the 2010 election, has officially endorsed Mitt Romney for president.

O’Donnell made her endorsement during an appearance this evening on Fox News’ “Hannity.”

“It was not an easy decision because I too think any of our candidates would make a great president and a great candidate going against Barack Obama,” O’Donnell said. “But I think there are certain tie breakers and I know that in making my decision I might be hurting some people but I think infrastructure and executive experience are important, and for that reason I’m endorsing Mitt Romney.”

O’Donnell made clear that the Romney campaign did not “come to her,” and that she went to the campaign. She said she would be willing to go out and campaign for Romney.

In a written statement, Romney welcomed the endorsement.

“Christine has been a leader in the conservative movement for many years,” Romney said. “Christine recognizes that excessive government threatens us now and threatens future generations, and I am pleased to have her on my team.”
