New York, NY —

Mayor Bloomberg says the nation needs to invest in its infrastructure to get the economy going again.

REPORTER: Appearing on NBC's Meet the Press Sunday, the mayor said President Obama needs to stop worrying about whether the spending is unpopular and show leadership by explaining to Congress and the people why it's necessary:

BLOOMBERG: The American public, even when they don't like what you do, if they think you're doing it from the heart, if they think you've got good ideas, if they think you've consulted and tried to build a consensus, and worked with people in a nonpartisan way, they're gonna come behind him.

REPORTER: Bloomberg appeared on the program with California Governor Arnold Schwarzenegger and Pennsylvania Governor Ed Rendell. The three met with President Obama Friday to advocate for infrastructure spending on things like transportation, ports, and levees... beyond what's in the stimulus package.
