Newark Mayor Cory Booker spoke to Rachel Maddow about being the Romney campaign's shield for Presdent Obama's attacks on Bain Capital.
Said Booker: "I am very upset that I am being used by the GOP this way and it's, uh, while I thought today I was going to be quiet, I've been pushed so far that you are going to hear a lot from me to the extent possible and to the extent that President Obama and his campaign want to hear from me."
First Read notes Booker is "clearly nervous about how this episode is playing with base Democrats."
