Tom and Jerry. Buggs Bunny and Elmer Fudd. Homer Simpson and Frank Grimes.
Those feuds are iconic in their own right, but U.S. Sen. Elizabeth Warren (D-MA) has a real life nemesis who she never misses a chance to attack when the opportunity presents itself.

On Tuesday, Warren blasted Federal Reserve Chairman Jerome Powell on her Twitter feed, laying the blame for the collapse of Silicon Valley Bank directly at his feet.
"Fed Chair Powell's actions directly contributed to these bank failures," Warren tweeted to her seven million followers.
As a member of the Senate Banking Committee, Warren's purview often directly intersects with Powell's job as head of the country's central bank, and he has been a frequent subject of her tweets.
She's called on him to pause interest rate hikes.
She has accused the Fed's interest rate hikes of being designed to intentionally crash the economy.
She has taken him to task for Wall Street malfeasance being business as usual.
Her punches aren't just confined to social media either. She had a couple of heated exchanges with Powell during his Senate testimony to the Senate Banking Committee just a week ago.
"You know, Chair Powell, you are gambling with people's lives. And there's a pile of data showing the price gouging and supply chain kinks, and the war in Ukraine are driving up prices," Warren said while questioning him about unemployment.
"You cling to the idea that there’s only one solution: lay off millions of workers. We need a Fed that will fight for families. And if you're not going to lead that charge, we need someone with the Fed who will."
