ABC News' Sunlen Miller reports: After his regular rounds of morning briefings, President Obama will hold a meeting with Cabinet secretaries, former secretaries of Transportation and mayors and governors on infrastructure investment in the State Dining Room. Senior administration sources say the president has been speaking to key members of Congress about the possibility of a $50 billion investment in infrastructure to help put people back to work and to improve the nation’s aging infrastructure. He’ll discuss the idea in person with mayors and governors from across the country today. Former Transportation Secretaries Mineta and Skinner will also attend and discuss their proposal which states that the U.S. needs an additional $134-194 billion a year to maintain the nation’s current infrastructure system and to expand it. Now is an optimal time to invest in infrastructure, said an administration official, because the U.S. has underemployed resources that can be used. After the meeting the president will then deliver a statement to the press in the Rose Garden. In the afternoon, the President will meet with the five students featured in the movie "Waiting for Superman" in the Oval Office along with director Davis Guggenheim. In the afternoon, the President will travel to Miami, Florida to raise money for the Democratic Party, the first in a series of fundraising stops the president will make this week, just three weeks to Election Day. Mr. Obama will deliver remarks at a DCCC reception and then at a dinner for the DCCC at a private residence in Miami. The President will return to Washington, DC in the evening.
