When Air Force One touched down in Houston today, there was a special visitor awaiting President Obama at the airport.
Sitting in a wheelchair at the George Bush Intercontinental Airport, President George H.W. Bush greeted the president and First Lady Michelle Obama.
Bush was seen wearing patriotic red, white and blue socks, while the Obamas stood next to him speaking for several minutes.
At times, the first lady held his hand, and President Obama touched Bush's shoulder. Bush patted the president's legs as they spoke.
President Obama is in Houston tonight for a pair of Democratic fundraisers.
Earlier in the day, President Obama spoke at a memorial service at Fort Hood.
