I think your needle jumped a groove or two. Hillary may not even have been born when McCarty was a Senator.
Hilary was part of the independent prosecutors team filing charges against Nixon, not McCarthy. (I think)
She was born during his time in the Senate, but she was all of 9 1/2 years old when he died in 1957.
I stand corrected as to the event in young Hillary’s legal career. However, such does not change my perusal of her career or future years that she was associated with some nefarious actions. I wouldn’t trust her or Bill Clinton to give me honest change for a 5 dollar bill or even a 1 dollar bill.
