Story highlights Biden has given varied answers about 2020

The group's initial materials strike out against "negativity" and "small-mindedness"

Washington (CNN) Former Vice President Joe Biden is launching a political action committee, which is set to kick into gear Thursday morning, a Biden aide tells CNN.

The group, "American Possibilities PAC," is sure to set off speculation about Biden's 2020 intentions.
