UPDATE (10:02 PM EDT):
Tamerlan Tsarnaev reportedly called his mother as police were shooting at him last Thursday night, shortly before his death.
The Wall Street Journal reports his mother said Tamerlan called her on Thursday night and said, "The police, they have started shooting at us, they are chasing us... Mama, I love you."
"Then the phone went silent," the Journal reports.
UPDATE (7:22 PM EDT):
EXCLUSIVE: Secret emails obtained exclusively by Breitbart News show the libertarian Cato Institute, Americans for Tax Reform, and Sen. Marco Rubio (R-FL) are colluding on immigration reform messaging in the wake of the Boston Marathon terror attack in order to push the “Gang of Eight” bill that was released this past week.
Okay, that's a big effin deal. I consider Breitbart a usually reliable source. If they have these emails, they need to print them...like NOW.
