The president held an unscheduled appearance yesterday to talk about the new economic measures, but he left without taking any questions. So theres still a lot of details that need to be worked out.

Hes also hoping to work on help for what hes calling hourly wage workers, he says, so they dont miss a paycheck. He wants to do loans for Small Businesses and talking about help in some form for the airline, cruise and hotel industry. The democrats are really hoping that the white house will focus on what theyre calling individuals, essentially real people, working American Families, but not even all republicans are on board with a payroll tax.

You mentioned it, four years ago Bernie Sanders was 20 points behind in the polls and upset Hillary Clinton.

Reporter its a daunting challenge for sure, george, for Bernie Sanders. Joe biden leading in the pulls.
