WASHINGTON (AP) - A White House official says President Barack Obama plans to attend next week's launch of space shuttle Endeavour.
 
He will be joined by his wife, Michelle, and daughters Malia and Sasha.
 
Obama had already planned to be in Florida that day to give a commencement address at Miami Dade College.
 
The April 29 launch is the next-to-last flight for the shuttle fleet. It will be led by Mark Kelly, the husband of Arizona congresswoman Gabrielle Giffords. Giffords was critically wounded during a shooting in Tucson in January and is awaiting clearance from her doctors to attend.
 
The White House official asked not to be named to speak freely ahead of a formal announcement about Obama's plans.
