(CNN) - Dan Quayle will throw his support behind GOP presidential hopeful Mitt Romney on Tuesday, CNN has confirmed.
The former Republican vice president, who served with former President George H.W. Bush, will make the announcement alongside Romney at an event in suburban Phoenix.
The endorsement comes a week after Romney met with Bush and his wife Barbara at their Houston-area home.
Quayle's son, Ben, is a congressman representing Arizona.
