Sen. Susan Collins (R-ME) publicly revealed for the first time on Wednesday that she has had an “extremely common” medical condition, called a benign essential tremor, for decades.

“What I have is an extremely common condition that is called a benign essential tremor. I have had it for the entire time that I have served in the United States Senate. It has absolutely no impact on my ability to do my job or on how I feel each day,” Collins said.
