Former President George H.W. Bush will formally announce on Friday his support of Republican Presidential candidate Mitt Romney. The announcement will be made at an event to be held in Houston, said campaign officials on Wednesday.

Bush, in an interview with the Houston Chronicle last December said, “I consider Romney the best choice.”

He had a meeting with Romney just prior to Christmas, but to date has not appeared publically at any campaign functions with the former governor of Massachusetts. The former president, who is 87, will join his son, Jeb the former governor of Florida in offering the Romney campaign his support. Jeb Bush to date has not done any campaigning for or with Romney.

George H.W. Bush’s son, George W. Bush has not made an endorsement or spoken publically about the candidates for the GOP presidential nomination. An official from the Romney campaign said neither George W. Bush nor Jeb Bush would be present at the event in Houston on Thursday.

Bush’s endorsement comes at a time when Romney is in the midst of two days of Texas fundraisers. His appearance on Thursday with Bush is the only public event Romney will hold during his two-day stay in the Lone Star State.

One of Romney’s fundraisers said that a fundraiser would be held after Romney’s appearance with Bush at the St. Regis Hotel in Houston. That particular fundraiser is expected to add $500,000 to Romney’s campaign war chest.

This week, Romney’s campaign officials have been coy about the event in Houston. At the endorsement ceremony, only pool reporters will be allowed to attend.
