Tick tock of the Sotomayor pick

From NBC's Kelly O'Donnell

Sources familiar with the process say President Obama called Sonia Sotomayor last night at 9:00 pm, and called the other potential picks after that.

Obama then called congressional leaders this morning.

Obama met with Sotomayor last Thursday -- she was at White House for seven hours and went undiscovered.

Aides say the president was "blown away by her -- her personal story, her sharp intellect and confidence, and her experience as prosecutor, trial judge, litigator and appellate judge."

Aides say she has more federal judicial experience than anyone on Supreme Court in 100 years.
