Former congressman Joe Sestak launches presidential campaign

Former Pennsylvania congressman Joe Sestak becomes the latest Democrat to enter the presidential race

PHILADELPHIA -- Former Pennsylvania congressman Joe Sestak has become the latest Democrat to enter the presidential race.

Sestak decries what he calls "America's retreat from the world" and says strong action is needed to deal with climate change, corporate accountability and China's geopolitical threat.

"The president is not the problem; he is the symptom of the problem people see in a system that is not fair and accountable to the people," Sestak said in his campaign video.

He said he delayed his entry into the presidential race while his daughter battled brain cancer, which returned after she first beat it at age 4.

"Throughout this past year, Alex again showed she is stronger than me, heroically beating the single digit odds once more, drawing on the fortitude of her mom," Sestak said.
