One-time Republican presidential candidate Newt Gingrich is asking the delegates he won during the GOP primary race to support the presumptive nominee, Mitt Romney.
In an open letter to delegates released Tuesday, Gingrich says it's time for all Republicans to come together to defeat President Barack Obama and Vice President Joe Biden.
Gingrich says he is releasing all delegates bound or pledged to his candidacy under any and all state laws or party rules.

A former speaker of the House, Gingrich won just two primaries, in South Carolina and his home state of Georgia. At one time he vowed to challenge Romney all the way to the nominating convention if Romney lacked a majority of delegates to win the nomination outright. But Romney gained the number of delegates he needed.
