Sad news to report out of Tennessee. The family of former Senator Fred Thompson announced that he passed away today in Nashville, reportedly from a recurrence of lymphoma, at age 73:

Thompson will not only be remembered for his work as a senator and presidential candidate, but also as an actor in such films as “The Hunt for Red October”…

And “Die Hard 2”:

Thompson’s last two tweet — as we’ve come to expect — were funny zingers that targeted enviro-zealot Richard Branson and gun-free zone laws:

That humor will be missed.

Thompson is widely credited with crafting the now infamous question “What did the president know and when did he know it?” while serving as counsel to the Senate Watergate Committee investigation of President Nixon.

Condolences are pouring in from all over Twitter:

Rest in peace.
