Meanwhile, the President unveils that much-talked about infrastructure plan today.

The White House hopes the money will trigger state and local governments to spend a total of $1.5 trillion on improvements.

2. Crashes

Meanwhile, three people died when a helicopter touring the Grand Canyon crashed in Arizona. Three survivors and the pilot were later rescued in an operation that was hampered by the windy and rugged conditions in the canyon.
