Clinton introduces first piece of a new jobs agenda

Hillary Clinton is promising hundreds of billions of dollars in new federal spending in an effort to compete with the liberal economic policies of her presidential primary challengers.

The first piece of a new jobs agenda, a $275 billion infrastructure plan unveiled Sunday, falls short of the $1 trillion pledged by Vermont Sen. Bernie Sanders to rebuild the nation's crumbling bridges, ports, highways, and airports.

But it marks an effort by Clinton to fulfill her party's desire to use national programs to boost the middle class without alienating independent voters more concerned with increasing the federal deficit.

Clinton aides said her economic initiatives will be the most expensive of her campaign and plan to roll out proposals for new investments in manufacturing and research in the coming weeks.
