While the inauguration of former President Barack Obama's public library was taking place, his colleague Bill Clinton was caught dozing.

The prying lens of one of the attendees at the opening of the venue where nearly $850 million dollars were invested, discovered the 79-year-old Democrat closing his eyes and resting his head on his left hand to prevent it from going sideways while listening to some speeches from the special guests at the event.

After five years of having begun the formal construction of the Obama presidential library and museum, it finally opened its doors in Chicago.

Bill Clinton and Hillary, his wife, coincided with the presidential couples of the Obamas, the Bushes and the Bidens, all of them gathered at the complex located in the historic Jackson Park neighborhood, on the South Side of Chicago.

Representing the Republican Party, the only one who attended was George Walker Bush, since Donald Trump apparently was not even invited.

The event was packed with celebrities such as: John Legend and his wife Chrissy Teigen, Stephen Colbert, Oprah Winfrey, Tom Hanks and his wife Rita Wilson, Tyler Perry, Steven Spielberg and former model Jill Vedder, to name a few.

Representing Democratic politicians, Nancy Pelosi, Kamala Harris, Gavin Newsom, J.B. Pritzker and Rahm Emanuel also attended the event.

However, of all of them, Bill Clinton was the one who captured the attention because of how tired he looked, raising questions regarding his health.

In August of last year, the former head of the nation was captured in the Hamptons, Long Island, and very close to him an assistant who accompanied him was carrying a portable defibrillator, a device used to send a current or electric shock to the heart to restore the heartbeat in case of a heart attack.

However, no one from his close circle offered details about any possible medical problem he had.

The point is that, every time he reappears publicly, he appears more tired for no apparent reason beyond his advanced age.
