Time magazine reported that the three other living former presidents — Jimmy Carter, George H.W. Bush and Bill Clinton — will also be in attendance. Bush's brother, former Florida Gov. Jeb Bush, and Clinton's wife, former Secretary of State Hillary Clinton, are expected to attend as well.
"President Obama and the First Lady look forward to participating in the formal opening of a library that will be dedicated to a president who led our country in difficult times at home and abroad," White House deputy press secretary Josh Earnest said in a statement.
"It’s difficult to fully comprehend what it’s like to serve as President of the United States unless you’ve done it – and President Obama has developed a good relationship with both President George W. Bush and President George H.W. Bush. He has routinely expressed his deep appreciation for the 43rd President’s commitment to this country we love, and is looking forward to returning to Texas later this month."
