Hillary Clinton Completely Spaces Out During Speech

Hillary Clinton completely forgot what she was talking about over the weekend.

In a Scranton, Pennsylvania, speech, Clinton criticized Bernie Sanders in front of a cheering crowd. The 68-year-old then passionately spoke about what she would do differently then Sanders as president.

"…We do not need another big contentious debate about healthcare," Clinton said. "We need to make what we've got work really well and improve it and the get the cost out of…upward spiral…now I want to mention two other things…"

The Democratic front-runner paused for a few seconds, losing her train of thought, then quickly powered on with her speech.

Clinton has raised questions about her health, continuously coughing in speeches and potentially suffering from post-concussion syndrome.

Donald Trump said only a month ago that he believed his likely general election opponent does not have the energy necessary for a U.S. president.

"I think she doesn't have the stamina," Trump said. "You watch her life, you watch how she'll go away for three, four days, she'll come back, and she'll go, I think she just doesn't have the stamina."

Did Clinton's misstep related to her health, stamina, or was it just a momentary brain freeze? Watch the video and sound off below.
